Splatter: The GEDCOM Population Distribution Heatmap
Splatter: The GEDCOM Population Distribution Heatmap is a free web service that will splatter all the locations in your database across the face of a fully featured Google Map. In Splatter, location markers are grouped into clusters and the total number of persons found within each cluster is displayed inside the cluster icon. These clusters are also represented on the surface of the world as a heat map. The initial view gives a great overview of the world wide distribution of the people in your database. Zooming in expands clusters and exposes location markers. Hovering over these displays a conversation bubble with the list of persons found there.
