Abstract. Volunteered geographic information (VGI) has been seen as useful
information in times of disasters. Several authors have shown that VGI is useful
for coping with preparedness and response phases of disaster management.
However, because it is still a young technology, the use of VGI remains
uncertain, due to its lack of strong reliability and validity. It is our assumption
that to improve reliability and validity the promotion of citizen engagement
(CE) is needed. CE is not new topic, but in the digital humanitarian context, it
involves important factors that are not yet considered by disaster managers, such
as communication processes, motivation of volunteers, different media for
production of information, etc. To ll this gap, we identied a set of preliminary
factors which should be considered to promote the involvement of volunteers in
disaster management. These factors were derived from critical review of CE
literature and from an analysis of lessons learned from an experiment on
interaction with citizens carried out in context of the EU-project DRIVER

1 Introduction
Citizen Engagement (CE) refers to actions designed to identify and address issues of
public concern [1]. Community participation can augment ofcialsabilities to govern
in a crisis, improve application of communally held resources in a disaster or epidemic,
and mitigate community wide losses [2].
Participatory community approaches in research and governance are not new [3,4].
However, Web 2.0 platforms, mobile internet, and social networking access through
smartphones have made a signicant difference by encouraging the social responsi-
bility and active engagement of citizens [3]. These technologies enable the public to
contribute and participate on an unprecedented scale and have led to many diverse

initiatives using information from citizens [3,4]. Examples include, among others,
participation of the public in event reporting, environmental monitoring, and providing
information on natural disasters. This phenomenon is called volunteered geographic
information (VGI).
VGI is the harnessing of tools to create, assemble, and disseminate geographic data
provided voluntarily by individuals [5]. VGI has been increasingly recognized by
researchers as an important resource to support disaster management [2325]. The
production of geographic information is predominantly made through social media
(e.g. Twitter, https://twitter.com/), crowd sensing (e.g. citizens equipped with smart-
phones can report about local conditions using dedicated applications) and online
mapping tools (e.g. OpenStreetMap, https://www.openstreetmap.org; Wikimapia http://
wikimapia.org/; Google Map Maker, https://www.google.com.br/mapmaker)[57].
Whilst those platforms can be potentially used to provide useful information for
dealing with disaster management, there are still many challenges to be addressed, for
instance: (i) how can people be encouraged to provide valuable information; (ii) how
can information from volunteers be validated; and (iii) how can this information be
integrated with other sources of data [6,8].
Many governments and agencies recognize the opportunities and challenges posed
by informal volunteers, and many have developed strategies and resources for engaging
and managing them. However, organizational culture, risks and liabilities impose
signicant barriers to greater involvement of informal volunteers in emergency and
disaster management [2].
Different VGI categories social media, crowd sensing, and collaborative mapping
activities require different strategies for promoting citizen engagement. It is our
assumption that knowledge of the VGI categories is relevant for disaster managers to
recruit and motivate users to utilize VGI-systems.
Additionally, works related to VGI in disaster management focus on production by
volunteers and the use of this information by disaster managers. They disregard the fact
that the production and consumption of VGI should be seen within a communication
process, i.e., the communication among the stakeholders should be multidirectional.
To help ll this gap, we present in this paper a preliminary set of key factors to help
promote the involvement of volunteers in the disaster management domain. These
factors were derived from review of CE literature and from an analysis of lessons
learned from a simulation exercise carried out in context of the EU-project DRIVER
Driving Innovation in Crisis Management for European Resilience. The DRIVER
project was launched in May 2014. This project, gathers the expertise of 37 organi-
zations, and will jointly develop solutions for improved crisis management. Repre-
sentatives from the security and defense industry, research and academia, SMEs,
end-users and several European institutions, from 13 EU member states and 2 asso-
ciated countries participate in this innovative venture.
With this work we aim to answer the following research question:
RQ. What factors should be considered by disaster managers to improve the
involvement of digital volunteers?
The remainder of this paper is organized as follows. First, in order to set a ground
on the different VGI approaches an overview is presented in Sect. 2. In Sect. 3we
present a review on the motivation and engagement of digital volunteers. In Sect. 4we
Improving the Involvement of Digital Volunteers in Disaster Management 215
present factors to improve citizen engagement, based on lessons learned from an
experiment on interaction with citizens carried out in context of the EU-project.
Finally, in Sect. 5, we conclude with nal remarks and give potential directions for
future works.
2 Volunteered Geographic Information
2.1 Volunteered Geographic Information VGI Source
In general, VGI in the context of disaster risk management can be collected through
different collaborative sources [6]: (i) social media; (ii) crowd sensing; and (iii) col-
laborative mapping activities.
The rst category of geo-information (i) involves the use of existing social media
platforms to exchange information in an unstructured way. These platforms enable
citizens to share self-produced content within a network of contacts or for the general
public [6]. Common social media platforms include Twitter; Facebook, https://www.
facebook.com/; Flickr, https://www.ickr.com/; YouTube, https://www.youtube.com/.
The second category of geo-information (ii) relies on citizens on the Web or
equipped with smartphones to act as sensors and share observations [6,10]. The term
crowd sensingis used to describe approaches that make use of specic software
applications to provide more precise structured data [6]. Ushahidi-based platforms and
mobile applications are the most commonly used in this category for data collection.
GDACSmobile, for instance, is a tool that facilitates the self-organization of volunteers
and improves the situational awareness of citizens by sharing an easy-to-understand
overview of the state of affairs. At the same time, GDACSmobile also provides a
feedback mechanism to the crisis manager/control center [11].
The third category of geo-information (iii) consists of a specic type of information
and collaboration platform: the collaborative editing of geographic features to fulll
internet-based interactive maps. Well-known platforms like OpenStreetMap (OSM),
Wikimapia and Google Map-Maker fall into this category [6].
Collaborative mapping activities are essential for disaster management, because they
collect a very specic type of data namely, georeferenced data about features like
streets and roads, buildings etc. and structures this information in the form of a map
[23]. The OpenStreetMap (OSM) project has great potential in disaster scenarios, which
was shown when a large number of volunteers provided their support in mapping events
after the 2015 Haiti earthquake [26,27] and the 2015 Nepal earthquake [23]. Collab-
orative mapping in OSM has emerged as a key mechanism through which individuals
can provide information about affected areas, thus making a tangible difference to aid
agencies and relief work without actually being physically present on-site [23].
2.2 VGI Types
Senaratne et al. [12], categorize the main types of VGI as (i) text-based VGI, (ii) im-
age-based VGI, and (iii) map-based VGI.
216 R. dos Santos Rocha et al.
Text-based VGI is generally produced implicitly on portals, such as Twitter or
various blogs, where people contribute geographic information in the form of text by
using smartphones, tablets etc. [12]. Twitter, for example is used as an information
foraging source [12,13]
Image-based VGI is generally produced implicitly within portals such as Flickr,
Instagram, etc., where contributors take pictures of a particular geographic object or
surrounding with cameras, smart phones, or any hand held device, and attach a
geo-spatial reference to it [12].
Map-based VGI covers all sources that include geometries as points, lines, and
polygons, which are the basic elements to design a map. Among others, OSM,
Wikimapia, Google Map Maker, and Map Insight are examples of map-based VGI
projects [12].
Table 1presents the relationship between sources and the different types of VGI.
2.3 Typology of VGI
Craglia et al. [3] introduced the concept of typology in VGI. According to these
authors, there are two modes through which individuals or communities contribute
such information: rst, the way the information was made available and second, the
way geographic information forms a part of it.
Each of these two dimensions can be explicitor implicit, with explicit denoting
that the dimension is of primary concern to the piece of VGI, while implicit denotes
that the dimension was not originally an integral part, and is of secondary concern [3].
Thus the topology of VGI proposed by Craglia et al. [3] is a matrix of four types of VGI
as shown in Table 2.

Geographic location is essential in disaster analysis [14]. Thus, only the explicit
geographic category explicitly- or implicitly-volunteered information of the VGI
typology is used in this paper.
Nevertheless, the typology of VGI proposed does not take in account the fact that
different VGI types have different translation needs, which this may imply excess noise
(e.g., many useless messages before a useful message to be found). For example, a
picture of a ooded area is more effective (i.e., it has less translation needs) for disaster
managers than a short message (tweet) describing the same ooded area.
Considering this aspect, we propose a new typology of VGI, which considers
different levels of uncertainty noise and translation needs. As can be seen, the explicit
VGI sources crowd sensing, and collaborative mapping activities have fewer
translation needs than social media data (Fig. 1).
3 Motivation and Engagement of Digital Volunteers
A Digital volunteer or a digital humanitarian is an individual that applies and leverages
their technical skills in collecting, processing and managing data in support of response
efforts for disasters [30]. In most cases, he/she is not physically present at the place
where the disaster has occurred. The Digital Humanitarian Network (DHNetwork)
grew out of this ecosystem of emerging technical volunteer involvement based
throughout the globe [29]. Since the 2010 Haiti earthquake, these communities have
provided support to formal humanitarian operations [27], and more recently have
provided a crucial compliment to operational organizations and governments active in
the eld [29].
Fig. 1. Typology of VGI considering different levels of uncertainty - noise and translation needs
218 R. dos Santos Rocha et al.
However, it is still a challenge to keep digital volunteers motivated and engaged for
longer periods, especially considering that they do not have strong connections to
events due to their digital presence instead of physical presence in affected areas. This
requires different ways to motivate and engage them to provide high quality contri-
butions in future crisis/disaster situations.
To deal with this critical issue, we propose in this section a rst attempt to
understand how motivation of digital volunteers can be understood using, for instance,
the Valence, Instrumentality, Expectancy (VIE) approach [17].
In general, volunteers are motivated by many incentives. Examples include, ide-
ology, personal satisfaction, community, and humanitarian values. Particularly, in the
context of a digital humanitarian, there is another factor that should be considered: the
desire to apply and improve technical knowledge. Considering that many of these
volunteers come from open source communities [28], why is it so important to
understand the incentives of citizens in order for them share their observations from the
eld? Considering the 90-9-1-Rule [31], there is a so called participation inequality.
According to this rule, in a collaborative online environment, 90% of the participants of
a community only view content, 9% of the participants edit content, and only 1% of the
participants actively create new content [31].
In addition to such factors, it is important to understand two specic questions:
(i) why does a citizen report an observation from the eld, and (ii) does the information
reported supports the decision making of disaster managers.
The rst question is related to behavioral aspects, i.e., what are the incentives of
citizens in order for them to want to share their observations from the eld? Literature
commonly understands incentives as instruments inuencing the behavior of members
of an organization or community in order to adapt to the organization wide system of
objectives [18]. By creating incentives, certain desired modes of behavior from indi-
viduals are promoted, enabling specic situational conditions which in turn result in the
activation of individual motives. In this case, a motive denotes a time-invariant psy-
chological disposition, i.e. an isolated, not yet activated incitement for the behavior.
Capelo et al. [28] highlight some important incentives:
Encourage volunteers by giving feedback, recognition, appreciation and gratitude;
Cultivate a sense of ownership and accountability. Team members have to know
that they matter, and that they are making a difference in the humanitarian
operation;
Generate a feeling of inclusivity based on a system of collaboration, partnership and
sharing with multiple stakeholders;
Provide training and capacity-building opportunities for volunteers.
The second question is related to the contribution of effort input. For instance, the
reporting of a ooded road is higher, if the reporter (or citizen) is affected or not.
According to the VIE approach [17], the effort input of an individual is high when it
expects that the contribution will yield results, which are rst important to the orga-
nization or community, secondly, due to the expected instrumentality, show close
relationships to individually aspired results from extrinsic incentives, and thirdly
exhibit valences as high as possible.

4 Lessons Learned to Improve the Involvement of Volunteers
In this section, we summarize the lessons learned to improve the involvement of
volunteers in the production of high-quality relevant information for disaster man-
agement. The elements presented here were derived from the VGI and citizen
engagement literature reviews, as well as the analysis of lessons learned from a eld
experiment carried out in the EU-funded demonstration project DRIVER.
The selection process of the literature was based on the experience of the authors of
this paper. Regarding the VGI literature, four main works were selected as an input to
identify the main characteristics that may affect the digital volunteersengagement:
Albuquerque et al. [6], Craglia et al. [3], Klonner et al. [14], Senaratne et al. [12].
Regarding motivation and engagement of volunteers, we selected Nielsen [31], Lawler
[17], and Capelo et al. [28] to understand the main aspects that should be considered in
the digital volunteersengagement.
The eld experiment was based on a storyline designed by practitioners. They
dened a ctitious disaster event based on past experience, which resulted in a more
realistic and relevant scenario compared to a more tool-friendly situation designed by
the tool providers. The experiments conducted in the DRIVER Interaction with
Citizenscampaign concentrate on the following functions (a more detailed description
of this experiment can be founded in Havlik et al. [33], Middelhoff et al. [32] and van
den Berg et al. [22]):
Provision of context-aware and timely information tailored to the specic needs of
different societal groups over various channels, in order to improve their under-
standing of the crisis situation and to minimize adverse impacts.
Context-aware (micro-) tasking of non-afliated volunteers to perform real and
virtual tasks.
Efcient gathering of situational information about an incident from volunteers.
Efcient usage of received information from volunteers to improve the situational
awareness of crisis managers and consequently their handling of the cri-sis.
In the following subsections, we will summarize the ndings into two categories:
(i) characteristics of VGI, and (ii) communication processes.
4.1 Characteristics of VGI
The characteristics of VGI origin, type and typology shown in Sect. 2have an
impact on citizen engagement.
In regard to the origin of VGI, crowd sensing and collaborative mapping activities
have the potential to promote citizen engagement, due the ways in which the infor-
mation is created.
Thus, we propose a typology of engagement based on ve levels of involvement
from volunteers in scientic work [20] and a typology of participation proposed by
Pretty and Hine [21]. At the rst level, citizens provide resources, while having only a
minimal cognitive engagement. This level is called basic. In second level, distributed
intelligencerelies on the cognitive ability of the participants. After some training, the
participants collect data or engage in minor interpretation activities. At this level,
220 R. dos Santos Rocha et al.
quality evaluation by the volunteers is crucial. The third level represents participatory
engagement, where users take part actively in the problem denition and data col-
lection. On the last level, self-mobilization, non-professionals collaborate with pro-
fessionals, and together, decide on a problem they want to focus on and the methods for
data collection. This allows for both the consideration of interests and motivation of the
volunteers. On this level, volunteers are not only experts, but also have the role of
facilitators [14,20].
As shown in Table 3, social media presents a basiclevel of engagement. This is
because of the nature of its contribution, i.e., social media is provided implicitly. All
other VGI sources, provided explicitly, require different strategies for citizen engage-
ment, since many have volunteers with different levels of knowledge and motivation.
4.2 Communication Process
The elements in the communication process determine the quality of communication.
A problem in any one of these elements can reduce communication effectiveness [15].
For instance, different perceptions of the message, language barriers, interruptions,
emotions, and attitudes can all reduce communication effectiveness. Therefore, a
feedback mechanism should be considered to promote the involvement of volunteers.
The existing literature on VGI focuses on the production of geographic informa-
tion, and the use of this information by disaster managers. It disregards the fact that the
production of VGI should be seen within a more effective communication process, i.e.,
the communication among the stakeholders should have to include a mechanism for
continuous feedback.
In the context of the DRIVER Project, tools were proposed that should address both
objectives for the benet of the community, and for individual members of the pop-
ulation according to the VIE approach. In a recent eld exercise, the software tool
GDACSmobile was used to communicate observations to crisis mangers
(community-objective). The personal objectives of members of the population were
addressed by sharing reports with the community as an information layer on a map of
the environment around the user. In this way, the users could assure themselves of their
safety in the situation and strengthen their situational awareness using map
representation.

Consequently, by acknowledging the perceptions of community members, a
common language visualizing interactions becomes a basic requirement for an
appropriate crisis communication environment. One way to establish a common lan-
guage is to use VGI systems in combination with commonly used information cate-
gories and according pictograms [22]. In the meantime, many different VGI tools are
available, having different pros and cons regarding particular tasks. However, as
mentioned above, the main challenge here is less a technical problem, but rather an
organizational one. According to the discussion on incentives, we identify a trustful
and open solution as most appropriate. However, it must be able to visualize benets
for the community, i.e. an easy- and fast-to-understand situation overview including a
connection to responding authorities. In order to do so, the information should be
structured and visualized respecting the communitiesattributes (like age distribution,
language, technical afnity, etc.).
5 Conclusion
Further research is still necessary for engaging volunteers in the production of
high-quality relevant information for disaster management. For instance, how can we
ensure that local communities are involved at a meaningful level in different phases of a
disaster? This could be achieved, for instance, by initiating a community group or by
providing training to volunteers to produce high-quality VGI. Moreover, how to
improve collaboration between formal humanitarian organizations and volunteer
technical communities (VTCs) should also be explored in future works.
Additionally, the different VGI categories require different strategies for promoting
citizen engagement, given that the knowledge of the VGI categories is relevant for
disaster managers to recruit and motivate users to utilize VGI-systems. Therefore, one
of the expected outcomes will be the development of a new framework for promoting
engagement of digital volunteers in the disaster management context.

... Volunteer relief organizations usually support official disaster management and state an important pillar in disaster response. However, disaster management is the primary responsibility of official civil protection and disaster management authorities and, at least in Germany, they are in charge of command and control in disaster events [6]. Consequently, volunteer relief organizations constitute an integrated part of official disaster response activities and are coordinated accordingly. ...
... Grafana is connected to the database and allows intuitive modification of dashboard components, such as charts, according to the needs of the users. In the simulation, the probability of helping at an operating site is predicted for each volunteer and every operating site (6). Therefore, internal volunteer states, observations of the environment, and the friend connections among the volunteers are evaluated and sent to the Python script whenever an agent enters the "ready to help" state (p. ...
... According to disaster managers, scales of many disasters would have turned out to be much more dramatic without the help of spontaneous volunteers [3,6]. However, these volunteers often coordinate their actions mainly based on information retrieved from social media platforms such as Facebook or Twitter. ...
... Especially for digital volunteers, the things that make them loyal in disseminating information even though they do not meet each other are the desire to use and improve technical knowledge, especially in ICT (Information Communication Technology) (Roberto et al., 2017). Volunteers become loyal to their community because several things influence them, such as ideology, personal satisfaction, community, and human values. ...

Natural disasters have always threatened the lives of humans and other creatures. One of the significant challenges for quickly responding to an earthquake is the need for precise and comprehensive information. Given that part of the environmental infrastructure is destroyed, quickly acquiring the required information is a serious challenge. Due to the ubiquity of smartphones, which have sensing, processing, and communication capabilities, this paper proposes CrowdBIG, a crowdsourcing-based architecture for information acquisition from the disaster environment. CrowdBIG architecture consists of four layers: sensing, fog, cloud, and application. Given that the reliability of crowdsourcing systems is dependent on the quality of user data, detecting malicious users, as well as scoring, and selecting useful users are of great importance. The CrowdBIG system is equipped with a reputation management component, which contains two sub-components: malicious user detection and user scoring. To evaluate the CrowdBIG system, first, we validate the information acquisition and dissemination workflow of the system using a scenario-based method. We then simulate the disaster environment through several well-known scenarios. The results show that CrowdBIG can detect malicious users appropriately. The CrowdBIG system can also score non-malicious users reasonably based on their usefulness and information completeness rates. The simulation results reveal that the reliability of the CrowdBIG system is 92%. Finally, the usability evaluation survey shows that more than 80% of the participants rated the usability of the proposed information-gathering tool as good or excellent.
... Despite the advantages of crowdsourcing, there are still issues and challenges regarding the integration of crowdsourced data into the decision-making processes. These are mostly related to concerns about the quality/reliability/credibility of the data [78,79], although certain strategies can be adopted to improve the performance of data contributors [80]. Still, government-led crowdsourcing initiatives have been recently launched in order to interact with citizens during emergency situations to collect real-time information and improve disaster response efforts [81,82]. ...

Smart technologies such as artificial intelligence, the Internet of Things, and other cyber-physical systems are often associated to Industry 4.0 given their potential for transforming current manufacturing and industrial practices. In particular, the significant potential of these technologies for increasing automation, improving communication and self-monitoring, and optimizing production overall for industries is well known. However, the influential power of these technologies is not bounded by these applications and has significant potential for fields such as disaster risk reduction and emergency management. In this context, the proposed chapter discusses several applications of digital technologies and innovations from Industry 4.0 in these fields, such as big data, the Internet of Things and machine learning techniques for big data analytics. Additionally, research and governance needs in this context are highlighted, as well as certain challenges to widespread and mainstream the reliable use of these technologies in disaster management.
... Al estar altamente integradas en la vida cotidiana, en particular de los habitantes de las urbes, las redes sociales y las tic móviles resultan útiles para comunicarse tanto en el círculo cercano como en grandes grupos. Los estudiosos del tema, en América Latina, categorizan el uso de estas plataformas de acuerdo con las posibilidades de ellas; así, Dos Santos Rocha et al. (2017) sugieren que las plataformas sociales, como Facebook y Twitter, se caracterizan por el intercambio, autogenerado y desestructurado, de información; también sugieren que hay una segunda categoría, para la cual hay una intención concreta, y que se vincula a tecnologías específicas, como los teléfonos inteligentes; en este caso, los usuarios son sensores que comparten información detallada en plataformas específicas para estructurar la información. Esta forma de información es la que responde de manera eficiente durante los desastres porque, aun cuando hay muchas plataformas creadas por diferentes usuarios, la información que se distribuye y comparte tiene un objetivo específico (Güiza y Stuart, 2017;Kleinhans et al., 2015). ...

Bali Island, well known as The Island of The Gods, is a top tourist destination. In 2017, Agung Volcano eruption causes lots of tourist canceled their visits to Bali due to excessive news about the danger to travel to Bali. This was the first research conducted to analyses impact of volcanic disaster to tourist visits using big data in Bali, Indonesia. This research uses big global database or big data to analyses the impact of web news to tourist visits to Bali due to Agung volcano eruption. Big data is a term that describes the large volume of data, both spatial and non-spatial that inundates the world on a day-to-day basis. Big data in this research were processed from The Global Database of Events, Language, and Tone (GDELT) Project. GDELT project monitors the world's broadcast, print, and web news from nearly every corner of every country creating a free open platform for computing on the entire world. The purpose of this research was to analyse the impact of news of Agung Volcano eruption to tourist visits to Bali in 2017. Every news data sets from every country, filtered, calculated and spatially analyzed to discover the timeline and impact of Agung Volcano eruption on tourist visits to Bali in 2017. Geographic Information Systems (GIS) were used for calculation and spatial analysis. The result shows that the number of tourist visits were declining during eruption in October until November 2017 but raised again in December. November has the highest number of news related to the eruption. After the eruption in December, the number of tourist visits start to rising due to the operational of the airport. The declining was caused by shutdown of Bali airport and travel warning policy from foreign country for their citizen to not to travel to Bali. Even though the number of tourist is declining in October and November, number of tourists visit on the same period in 2017 were higher than 2016.

This chapter delves at the ways in which ML enhances the prediction and prevention of natural disasters. Disaster forecasts can be more accurate and timely with the use of machine learning algorithms that combine massive amounts of data from satellite images, seismic activity, and weather patterns. It is possible to foretell the occurrence of natural catastrophes using ML techniques, such as supervised, unsupervised, and deep learning models. As part of its ML implementation, it checks for issues with data quality, model interpretability, and processing limitations in real time. This chapter takes a look at the potential directions that machine learning ethics, real-time decision-making, and multimodal data integration could go in the future. Using case studies and real-world examples, this chapter discusses the possibilities and constraints of machine learning in mitigating natural disasters

The EU FP7 project DRIVER conducts a number of experiments that explore new approaches for addressing known deficiencies in crisis management. The “Interaction with Citizens” experiment campaign focuses on testing the usability and acceptance of various methods and tools that facilitate crisis communication via several channels. These include: informing, alerting, micro-tasking, incident information crowdsourcing from volunteers, and usage of this information to improve situational awareness. The results highlight that volunteer motivation in a serious game like scenario is important to simulate participation in crisis events. We also argue that the scenario complexity level needs to be simple enough to avoid difficulties in communication with non-professional participants in addition to external influences in a field experiment. In this paper, we present lessons learned from the final experiment of this campaign that investigated two-way communication solutions between crisis managers and citizens or unaffiliated volunteers in a simulated flooding scenario in the city of The Hague.

In this article we explore how pictograms and assessment categories used by crisis management organizations support the crisis communication with the affected population. In this field exercise simulating a flooding event the exemplary tool GDACSmobile was used to let volunteers report their observations to the crisis management center using a report in which they assigned the category they believed was most fitting to the situation they reported. Despite volunteers reporting difficulty in selecting a fitting category, their actual decisions were highly fitting the intended categories defined by the crisis managers. We learned that pictograms and categories have potential as a common language between crisis managers as well as the affected population supporting the process of an effective crisis communication.

With the rise of new technologies, citizens can contribute to scientific research via Web 2.0 applications for collecting and distributing geospatial data. Integrating local knowledge, personal experience and up-to-date geoinformation indicates a promising approach for the theoretical framework and the methods of natural hazard analysis. Our systematic literature review aims at identifying current research and directions for future research in terms of Volunteered Geographic Information (VGI) within natural hazard analysis. Focusing on both the preparedness and mitigation phase results in eleven articles from two literature databases. A qualitative analysis for in-depth information extraction reveals auspicious approaches regarding community engagement and data fusion, but also important research gaps. Mainly based in Europe and North America, the analysed studies deal primarily with floods and forest fires, applying geodata collected by trained citizens who are improving their knowledge and making their own interpretations. Yet, there is still a lack of common scientific terms and concepts. Future research can use these findings for the adaptation of scientific models of natural hazard analysis in order to enable the fusion of data from technical sensors and VGI. The development of such general methods shall contribute to establishing the user integration into various contexts, such as natural hazard analysis.

With the ubiquity of advanced web technologies and location-sensing hand held devices, citizens regardless of their knowledge or expertise, are able to produce spatial information. This phenomenon is known as volunteered geographic information (VGI). During the past decade VGI has been used as a data source supporting a wide range of services, such as environmental monitoring, events reporting, human movement analysis, disaster management, etc. However, these volunteer-contributed data also come with varying quality. Reasons for this are: data is produced by heterogeneous contributors, using various technologies and tools, having different level of details and precision, serving heterogeneous purposes, and a lack of gatekeepers. Crowd-sourcing, social, and geographic approaches have been proposed and later followed to develop appropriate methods to assess the quality measures and indicators of VGI. In this article, we review various quality measures and indicators for selected types of VGI and existing quality assessment methods. As an outcome, the article presents a classification of VGI with current methods utilized to assess the quality of selected types of VGI. Through these findings, we introduce data mining as an additional approach for quality handling in VGI.

A rising number of people is affected by disasters, such as the 2010 Haiti earthquake, the 2013 Philippines super-typhoon, and the 2015 Nepal earthquake. In the immediate aftermath of a disaster, humanitarian decision makers have to assure that action is prompt and targeted although confronted with lack of needed information about the highly complex and dynamic operational context in the affected area. Mobile technology and crowdsourcing have emerged as technologies that can help supply much needed information. GDACSmobile is a mobile-enabled IT solution for the assessment of needs, issues of access, infrastructure damage and other cross-cutting operational issues. In contrast to similar tools, e.g. Ushahidi or KoBoToolbox, GDACSmobile is an integrated solution addressing both the general public and professional responders, which closes the information cycle between disaster managers and the affected population. After all, most first responders are local citizens. In this paper, we introduce the context of the application and its concept, including descriptions of user groups and information flows that enable effective quality control of information. Subsequently an application scenario based on the 2015 Nepal Earthquake illustrates the value of using GDACSmobile to involve logisticians and assessment experts to inform and control the processes of data collection and information analysis, wherein professional responders and citizens act as primary data sources.

In the aftermath of a disaster, there is an urgent need for base maps to support relief efforts, especially in developing countries. In response to this, the OpenStreetMap project has been leveraged to produce maps of disaster-affected areas in a collaborative way. However, there has been little investigation aimed at explaining the collaborative mapping activity itself. This study presents an exploratory case study on how the collaborative mapping activities that followed the Nepal Earthquake in 2015 were coordinated and structured, i.e. how volunteers were organized, and what were the main outcomes of their activity in the context of disaster management. The results show that a large number of remote contributors spread across the world carried out concerted efforts to support the relief work. Moreover, coordination mechanisms were used by local actors to share their knowledge with remote mappers, and, hence, to improve the accuracy of the map.

Volunteered geographic information (VGI) refers to the widespread creation and sharing of geographic information by private citizens, often through platforms such as online mapping tools, social media, and smartphone applications. VGI has shifted the ways information is created, shared, used and experienced, with important implications for applications of geospatial data, including emergency management. Detailed interviews with 13 emergency management professionals from eight organisations across five Australian states provided insights into the impacts of VGI on official emergency management. Perceived opportunities presented by VGI included improved communication, acquisition of diverse local information, and increased community engagement in disaster management. Identified challenges included the digital divide, data management, misinformation, and liability concerns. Significantly, VGI disrupts the traditional top-down structure of emergency management and reflects a culture shift away from authoritative control of information. To capitalise on the opportunities of VGI, agencies need to share responsibility and be willing to remain flexible in supporting positive community practises, including VGI. Given the high accountability and inherently responsive nature of decision making in disaster management, it provides a useful lens through which to examine the impacts of VGI on official authoritative systems more broadly. This analysis of the perceptions of emergency management professionals suggests changes to traditional systems that involve decentralisation of power and increased empowerment of citizens, where value is increasingly recognised in both expert and citizen-produced information, initiatives and practises.
