Cover Story: Maps and spatial data are often produced by collaborative projects that welcome contributions from anyone. By nature, these projects are vulnerable to cartographic vandalism, which is the act of deliberately damaging spatial data and maps. Malicious content infiltrating spatial data projects lower the quality of and trust in user-generated map data, which are increasingly used by the technology industry for background mapping, navigation, and beyond. To combat cartographic vandalism, understanding its nature is crucial. We used a data-driven approach to analyze the spatial, temporal, and semantic aspects of carto-vandalism using OpenStreetMap and Pokémon GO as analysis platforms. The characteristics of carto-vandalism identified in this research can be used to improve vandalism detection systems in the future.View this paper.

Many real-world spatial systems can be conceptualized as networks. In these conceptualizations, nodes and links represent system components and their interactions, respectively. Traditional network analysis applies graph theory measures to static net...

Spatial perception is formed throughout our entire lives. Its quality depends on our individual differences and the characteristics of the environment. A sketch map is one way of visualising an individual’s spatial perception. It can be evaluat...

Comparison of Relief Shading Techniques Applied to Landforms

  • Marianna Farmakis-Serebryakova and
  • Lorenz Hurni

As relief influences disposition of all the other objects displayed on maps, terrain representation plays one of the key roles in the map creation process. Originally a manual technique, relief shading creates the three-dimensional effect and allows...
