Abstract

MInDSEt, or the Mindanao Integrated Data Sharing Environment, is an online geospatial data and information sharing facility/geospatial data infrastructure established in Caraga State University, Philippines. MInDSEt was developed using Geoserver for data storage and OGC services, and Geonode for data cataloguing and visualization. It was originally developed as data sharing facility of the stakeholders of the Geo-SAFER Mindanao, an R&D program which focused on generating detailed flood hazard maps of flood-prone river basins and watersheds in Mindanao, Philippines through numerical simulations using LiDAR-derived elevation datasets. Initially, MInDSEt was aimed to cater the needs for LiDAR-derived datasets (DTM, DSM) and flood hazard information (e.g., maps and GIS files) for Mindanao, as well as a venue to data sharing of its stakeholders that includes Geo-SAFER Mindanao implementing educational institutions and Local Government Units. Recently, MInDSEt's functionality was expanded to allow registered organizations and users to store and share any kind of geospatial data and information. One of the features of MInDSEt is its capability to categorize stored datasets as restricted (i.e., a specific organization or member of that organization can only access the data/information), controlled (i.e., data/information can be accessed by an organization or user after approval of data request), or public (i.e., anyone, even unregistered users can access the data. MInDSEt is also capable of handling externally stored data/information, wherein only the links to the external data/information are stored instead of the data/information files. This capability is advantageous to accommodate a greater amount of data/information with minimal effect to the facility's data storage. Through MInDSET, it is envisioned that geospatial datasets and information of Mindanao and for Mindanao will be come easily accessible by anyone.

ABSTRACT: MInDSEt, or the Mindanao Integrated Data Sharing Environment, is an online geospatial data and
information sharing facility/geospatial data infrastructure established in Caraga State University, Philippines.
MInDSEt was developed using Geoserver for data storage and OGC services, and Geonode for data cataloguing and
visualization. It was originally developed as data sharing facility of the stakeholders of the Geo-SAFER Mindanao,
an R&D program which focused on generating detailed flood hazard maps of flood-prone river basins and watersheds
in Mindanao, Philippines through numerical simulations using LiDAR-derived elevation datasets. Initially, MInDSEt
was aimed to cater the needs for LiDAR-derived datasets (DTM, DSM) and flood hazard information (e.g., maps and
GIS files) for Mindanao, as well as a venue to data sharing of its stakeholders that includes Geo-SAFER Mindanao
implementing educational institutions and Local Government Units. Recently, MInDSEt’s functionality was
expanded to allow registered organizations and users to store and share any kind of geospatial data and information.
One of the features of MInDSEt is its capability to categorize stored datasets as restricted (i.e., a specific organization
or member of that organization can only access the data/information), controlled (i.e., data/information can be
accessed by an organization or user after approval of data request), or public (i.e., anyone, even unregistered users
can access the data. MInDSEt is also capable of handling externally stored data/information, wherein only the links
to the external data/information are stored instead of the data/information files. This capability is advantageous to
accommodate a greater amount of data/information with minimal effect to the facility’s data storage. Through
MInDSET, it is envisioned that geospatial datasets and information of Mindanao and for Mindanao will be come

1. INTRODUCTION
Accessing and sharing, over the internet, relevant multisource and distributed geospatial data is crucial to support
decision makers in reducing disaster risks (Sterlacchini et al., 2018). Such is the case of the MInDSEt, or the Mindanao
Integrated Data Sharing Environment, an online geospatial data and information sharing facility and geospatial data
infrastructure established in Caraga State University, Philippines.
From 2017-2019, the Caraga State University implemented the Geo-SAFER Mindanao Program, or “Geo-Informatics
for the Systematic Assessment of Flood Effects and Risks toward a resilient Mindanao (Geo-SAFER Mindanao,
2017), with support from the Philippines’ Department of Science and Technology Philippine Council for Industry,
Energy and Emerging Technology Research and Development (DOST-PCIEERD). With a total of five projects under
it, the program aims to conduct detailed flood hazard mapping of flood prone river systems in Mindanao Island,
Philippines (Figure 1) using LiDAR-derived data products such as Digital Terrain Model (DTM) and Digital Surface
Model (DSM) and application of relevant GIS and flood modeling and hazard mapping methodologies and
approaches. To ensure that outputs of the program are easily accessed by the end users and stakeholders, it was
necessarily to establish a data sharing facility that will serve as the storage of the program’s outputs. This facility is
called MInDSET, and its establishment was seen to play a big role for the sustainability of the program outputs and
services. One of the objectives of the program is to distribute these outputs and make them available anytime to end
users and stakeholders for disaster management, land use planning, and related applications.
Initially, MInDSEt was aimed to cater the needs for LiDAR-derived datasets (DTM, DSM) and flood hazard
information (e.g., maps and GIS files) for Mindanao, as well as a venue to data sharing of its stakeholders that includes
Geo-SAFER Mindanao implementing educational institutions and Local Government Units (Figure 2). Recently,
MInDSEt’s functionality was expanded to allow registered organizations and users to store and share any kind of
geospatial data and information. The objective of this paper is to present details and capabilities of MInDSEt as an
integrated data sharing environment for Mindanao, Philippines.

2. DEVELOPMENT OF MInDSEt
MInDSET was developed using Geoserver for data storage and OGC services, and Geonode for data cataloguing and
visualization. By utilizing the data management tools built into GeoNode, MInDSEt was able to benefit the integrated
creation of data, documents, link to external documents and map visualizations. Each dataset in the system can be
shared publicly or restricted to allow access to only specific users.
MInDSEt comes with a portal that is accessible at http://mindset.ccgeo.info:81/ (Figure 3). Through this portal,
stakeholders, and the community of end-users, both from private and government sectors can collaborate, have access
to and/or exchange of datasets and information not limited to flood hazards. Primarily, this application was expected
to serve as a portal to simplify the request and download of numerous raw and processed geoscientific resources of
Mindanao.

3. FUNCTIONALITIES AND CAPABILITIES OF MInDSEt
3.1 Accessing MInDSEt
A user does need to register to search datasets in MInDSET.
The type of users can either be of the following:
Public User a user that is not registered or logged in to the portal.
Registered User (Insider) a registered user who is a member of a certain organization.
Registered User (Outsider) a registered user who wants to gain access to the controlled datasets
(organization specific datasets) of another organization.
Registered User (Others) a registered user who requests access/download only to the publicly available
and controlled datasets (organization specific datasets). This type of user cannot upload datasets.
Content Manager a registered user who is assigned by the Super Admin as the head of a certain organization.
This user also provides a listing of the possible users from their organization.
Super Admin - a user who has the universal access of the portal.
All datasets uploaded are searchable. Also, many of the datasets are readily downloadable, particularly datasets on
flood hazards. If a dataset, e.g., a LiDAR-derived DTM, is not downloadable (i.e., restricted), it requires a user to
register first. A restricted data can either be of the two: it can only be accessed by registered users (i.e., a user can
download it once registered and signed-in), or a data that requires a registered user to request access to it. If the latter
is the case, a form needs to be accomplished by the user indicating the reason for requesting access to the file.

3.2 Application Interface
There are several web pages that the user must interact with in the web portal. There are pages which shares common
toolbar while other varies depending on the type of information shown. There are buttons and links that are only
available for authenticated users and site administrator which may not be available for public users. Basically, each
page consists of the Portal Banner, Navigation Toolbar, Page Contents, and the Page Footer. The Navigation Toolbar
contains quick links to view spatial data, maps, documents, and quick search fields. Sign In and Register links are
also available in the said toolbar. The Content Area, essentially shows a variety of information related to geospatial
data uploaded, its metadata and other geoscientific information.
The Search page contains a wealthy of options for customizing a search for various information on this portal (Figure
4). While a simple search box is available at the top of every page, this search form allows for much more fine-tuned
searches.

3.2 Stored Datasets
MInDSEt can store both spatial and non-spatial (document) data sets covering various watershed as well as provinces
and municipalities of Mindanao (Figure 5). Among the data sets already uploaded in MInDSET are the following:
LiDAR-derived DTM
LiDAR-derived DSM
Flood Hazard Layers for various scenarios (Vector)
Flood Hazard Maps for various scenarios (Image)
Building Footprints
Roads
Tree Plantations
Technical Reports

MInDSEt is also capable of handling externally stored data/information (referred to as “external resource”), wherein
only the links to the external data/information are stored instead of the data/information files. For example, an
archived GIS shapefile (in zip format) is stored in Google Drive, and the link to this Google Drive is the one “uploaded”
in MInDSEt (Figure 6). This capability is advantageous to accommodate a greater amount of data/information with
minimal effect to the facility’s data storage. When a user accesses this data, and assuming the user is entitled to access
the data, the user will be directed to the Google drive file. The only disadvantage here is when the Google Drive file
is restricted, such that the Data Manager still need to approve the Google Drive access request sent by the user.

Planning in advance to prepare for and respond to a natural hazard-induced disaster-related emergency is a key action that allows decision makers to mitigate unexpected impacts and potential damage. To further this aim, a collaborative, modular, and information and communications technology-based Spatial Data Infrastructure (SDI) called SIRENE—Sistema Informativo per la Preparazione e la Risposta alle Emergenze (Information System for Emergency Preparedness and Response) is designed and implemented to access and share, over the Internet, relevant multisource and distributed geospatial data to support decision makers in reducing disaster risks. SIRENE flexibly searches and retrieves strategic information from local and/or remote repositories to cope with different emergency phases. The system collects, queries, and analyzes geographic information provided voluntarily by observers directly in the field (volunteered geographic information (VGI) reports) to identify potentially critical environmental conditions. SIRENE can visualize and cross-validate institutional and research-based data against VGI reports, as well as provide disaster managers with a decision support system able to suggest the mode and timing of intervention, before and in the aftermath of different types of emergencies, on the basis of the available information and in agreement with the laws in force at the national and regional levels. Testing installations of SIRENE have been deployed in 18 hilly or mountain municipalities (12 located in the Italian Central Alps of northern Italy, and six in the Umbria region of central Italy), which have been affected by natural hazard-induced disasters over the past years (landslides, debris flows, floods, and wildfire) and experienced significant social and economic losses.
