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.
