“This short paper reviews and clarifies the concept of heat maps for data visualization on cartographic maps. We show how heat maps can serve as a tool for powerful data exploration by presenting a practical example taken from the context of volunteered geographic information. In particular, we demonstrate how heat maps can help to get an overview over the users’ contribution behavior of information in the OpenStreetMap community with respect to a geographic space.”
