Article
Maps are good at representing geographic space, but texts have a stronger affordance of telling a story than maps. Telling stories is, however, important to make information more personal and to arrest the map user's attention. This paper contrasts the map and the text media in order to understand why texts are good at telling a story but conventio...
Conference Paper
Full-text available
Data is spatial if it contains references to space. We can easily detect explicit references, for example coordinates, but we cannot detect whether data implicitly contains references to space, and whether it has properties of spatial data, if additional semantic information is missing. In this paper, we propose a graph model that meets typical pro...
Thesis
Full-text available
Information is called spatial if it contains references to space. The thesis aims at lifting the characterization of spatial information to a structural level. Tobler's first law of geography and scale invariance are widely used to characterize spatial information, but their formal description is based on explicit references to space, which prevent...
Conference Paper
Full-text available
Geographical information science (GIScience) has, as a young and interdisciplinary field in information science, demands different than the one’s in other disciplines. Other fields have observatories and labor- atories to solve their specific problems, but GIScience has not. The concept of observatories cannot be transferred to GIScience without fu...

Full-text available
Maps, like other types of extensive data collections, are usually created and maintained by a larger number of individuals. The number of individuals using the map is even larger in most cases. Considering the complex interaction of these people, the question arises as to why maps can be used meaningfully. Ultimately, the represented geographical r...
Article
Full-text available
Place is a concept that can hardly be formally captured at the moment, as it is unclear how instances of places can formally be represented and how conclusions about places can practically be drawn by technological means. Geographical Information Science scholars hence tend to use the term ‘Place’ even when, in fact, they presume a paradigm similar...
Conference Paper
Full-text available
People “live” and constitute places through recurrent practices and experience. Both agency and experience are rooted in cultural embeddings that vary across different world regions. The complexity this entails requires researchers to investigate the concept of place through a variety of cultural lenses. The formal representation of place in GIScie...

Editorial for the Special Feature on Interdisciplinary Perspectives on Place.
Conference Paper
Full-text available
Maps represent a host of geographical features, but places are usually not among those depicted in detail. This is despite the various functions of a map, many of which refer to places as the common context in which geographical features are used, receive meaning, and even gain identity. Using the example of two sports venues, this paper explores t...
Article
Full-text available
Few laws about geographical information are known, partly because geographical information is inherently complex. Tobler’s first law of Geography and, to a lesser degree, also his second law are among the rare exceptions. In this article, we explore the validity of Benford’s law in the context of the example of OpenStreetMap. More specifically, we...
Article
Full-text available
Tectonic plate motion affects coordinates resulting from GPS measurements and the referencing of aerial and satellite imagery. It therefore impacts the long-term use of global coordinate systems. Over time, the tectonic plates move relative to each other and coordinates become outdated. Most geographic datasets including OpenStreetMap are no except...
Article
Full-text available
Geographical features can be represented in different ways. Buildings, for instance, can be represented as areal features defined by polygonal lines or as point features in a map. While the type of representation chosen to represent a building strongly depends on the scale of the map, it seems common to represent points of interests (POIs) as point...
Article
Full-text available
The naïve algorithm for generating nearest-neighbour models determines the distance between every pair of nodes, resulting in quadratic running time. Such time complexity is common among spatial problems and impedes the generation of larger spatial models. In this article, an improved algorithm for the Mocnik model, an example of nearest-neighbour...
Article
Full-text available
Epidemics and pandemics are geographical in nature and constitute spatial, temporal, and thematic phenomena across large ranges of scales: local infections with a global spread; short-term decisions by governments and institutions with long-term effects; and diverse effects of the disease on many aspects of our lives. Pandemics pose particular chal...
Conference Paper
Full-text available
People ‘live’ and constitute places every day through recurrent practices and experience. Our everyday lives, however, are complex, and so are places. In contrast to abstract space, the way people experience places includes a range of aspects like physical setting, meaning, and emotional attachment. This inherent complexity requires researchers to...
Conference Paper
Full-text available
People perceive the environment in various idiosyncratic ways, letting them conceptualize places differently. Representation in a data set and communication about places, however, create the need to reach agreement in the place a symbol or word represents. People have thus to integrate their views about a place. In this paper, we discuss how idiosy...

Full-text available
This editorial presents a special collection of papers addressing the concept of place and its use in geographical information science (GIScience). The concept of place is a topic of increasing interest among GIScience scholars. First attempts to formalize platial information have been made and it is increasingly held that user‐generated data sets...

People share data in different ways. Many of them contribute on a voluntary basis, while others are unaware of their contribution. They have differing intentions, collaborate in different ways, and they contribute data about differing aspects. Shared Data Sources have been explored individually in the literature, in particular OpenStreetMap and Twi...
Article
Full-text available
OpenStreetMap (OSM) is a collaborative project collecting geographical data of the entire world. The level of detail of OSM data and its data quality vary much across different regions and domains. In order to analyse such variations it is often necessary to research the history and evolution of the OSM data. The OpenStreetMap History Database (OSH...

Map-based navigation is a diverse task that stands in contradiction to the goal of completeness of web mapping services. As each navigation task is different, it also requires and can dispense with different map information to support effective and efficient wayfinding. Task-oriented reduction of the elements displayed in a map may therefore suppor...

The concept of “place” is about to become one of the major research themes in the discipline of geographical information science (GIScience), as well as in adjoining fields. Briefly put, while locations provide objective references (e.g., point coordinates), places are the units utilized by humans to approach the geographic world. The PLATIAL’18 wo...

Article
Full-text available
The fact that an increasing number of people and local authorities are affected by natural hazards, especially floods, highlights the necessity of adequate mitigation and preparedness within disaster management. Many governments, though, have only insufficient monetary or technological capacities. One possible approach to tackle these issues is the...
Conference Paper
Full-text available
The fitness for purpose concerns many different aspects of data quality. These aspects are usually assessed independently by different data quality measures. However, for the assessment of the fitness for purpose, a holistic understanding of these aspects is needed. In this paper we discuss two Linked Open Data vocabularies for formally describing meas...
Article
Full-text available
Many complex networks expose global hub structures: for some nodes, the number of incident edges far exceeds the average, leading to a small average shortest path length. Such ‘small-world properties’ are often guided by a scale-free power-law distribution of the node degrees, and self-organization inside the network has been identified as a reason...
Article
Full-text available
Data quality and fitness for purpose can be assessed by data quality measures. Existing ontologies of data quality dimensions reflect, among others, which aspects of data quality are assessed and the mechanisms that lead to poor data quality. An understanding of which source of information is used to judge about data quality and fitness for purpose...
Article
Geospatial data is often spatially aggregated by the use of Discrete Global Grid Systems. References to grid cells are needed for the communication of such data, and different identifier schemes have accordingly been introduced in literature. These schemes suffer, however, from being hard to understand for non-experts, and the geometry of a cell ca...
Conference Paper
Full-text available
The tectonic plates of the Earth shift relative to each other, which creates the need to adapt coordinate values on a regular basis. However, such systematic adaptions are not carried out in case of the OpenStreetMap dataset, which should render possible to trace this effect within the dataset. We empirically demonstrate that the effect cannot be t...

Space and time both play a major role in the evolution of traditions. While it is known that processes at different scales guide the evolution of culture, it is not yet clear which structural factors promote the emergence and persistence of traditions. This paper argues that the principle of least effort is among the factors that foster traditions,...
Article
Full-text available
OpenStreetMap and other Volunteered Geographic Information datasets have been explored in the last years, with the aim of understanding how their meaning is rendered, of assessing their quality, and of understanding the community-driven process that creates and maintains the data. Research mostly focuses either on the data themselves while ignoring...

Spatial variance is an important characteristic of spatial random variables. It describes local deviations from average global conditions and is thus a proxy for spatial heterogeneity. Investigating instability in spatial variance is a useful way of detecting spatial boundaries, analysing the internal structure of spatial clusters and revealing sim...

Street networks have been examined in respect to their structure. The author of this paper has previously examined networks from various domains, thereby demonstrating that the polynomial volume law applies to many of them. This paper focuses on the geographical domain only. Thereby, it examines the dimension of street networks, which turns out to...

Full-text available
The comprehension of folksonomies is of high importance when making sense of Volunteered Geographic Information (VGI), in particular in the case of OpenStreetMap (OSM). So far, only little research has been conducted to understand the role and the evolution of folksonomies in VGI and OSM, which is despite the fact that without a comprehension of th...

Full-text available
Different definitions of data quality and fitness for purpose exist in literature. We propose definitions that align well with existing definitions but emphasize how both concepts relate.
Conference Paper
Full-text available
Data and the context in which data is interpreted are subject to imperfection, and the interpretation of the data accordingly depends on the choice of the context. Data quality and fitness for purpose can thus not be assessed without any choice of a context, a fact that can be regarded as an inevitable calibration of the data quality assessment. Th...

Space exposes certain characteristics, e.g., the notion of neighbourhoods, triangle equality, etc. Networks that are embedded in space inherit properties from space and are thus different to many other networks. I explore such properties in a network as well as how these need to be reflected in algorithms. In the long term, the project will lead to a better understanding of how structure reflects semantic information about things in space and thus improve big geospatial data applications.
