Résumé
Points of Interest (POI) are used for a variety of analysis tasks in planning, navigation, transportation, tourism, and other areas. For these tasks an understanding of the quality of POI data from different sources is essential. This paper reviews the temporal development and relative completeness of POI from proprietary (TomTom, NAVTEQ, ESRI) and free governmental (TIGER/Line) data sources, as well as that of Volunteered Geographic Information (OpenStreetMap). It highlights the pros and cons for each of these data sets in terms of completeness and currentness. It further analyzes for a subset of features how active the OSM community is in editing and updating previously imported POI from alternative data sources.
