Exploring Clusters in Geospatial Datasets
Analyzing multivariate geospatial data is a non-trivial task. Geographical location is a variable in itself that might be correlated with other fields in the data. When looking at the variable distribution in a geographical region, users often need to identify areas where the variable is overrepresented. We call such local maxima "hotspots" and present Fervor: a hotspot explorer. Fervor visualizes hotspots as a continuous heat map and offers a range of tools to investigate relationships within the underlying data. This project was continued and extended into ICE.
