This module allows you to easily create "heatmap" overlays to visually analyse the distribution of a set of point data. Heatmap layers can be customised by changing the intensity and radius of the heatspot created around
each datapoint, together with custom colour gradients including alpha transparency.
Added Feature tester sample app
- Updated function that sets option to regenerate color map when new gradient specified.
- Added second parameter to SetOption function to refresh heat map after setting options.
Bug fix for when canvas is added to map too early
Bug fix for map wrapping functionality that has points out of view on second map but should be in view on first map
