Heatmap report (Stamen Design Terrain map tiles)

Heatmap is a web report which creates an interactive map containing a heatmap generated from Gramps event place data.

Usage

Once this Report addon has been installed, Heatmap web pages can be generated from the Graphical User Interface or the Book interface. Report only looks for Places found within a subset of the Events related to a group of People.

The webpage contains an embedded list of GPS coordinates for places with the number of Events occurring at each place. The list is set up for output to the Heatmapping overlay feature of a selected Web map service.
