Heat Map Layer Revisited
Following this post, Glenn G. found an "issue" when panning the map. I revisited the project and indeed there was a bug. Thanks Glenn. I updated the project and here is the result. In this project, I downloaded from geonames all cities with population over 15000 and plotted them on the map. The clustering of the cities (over 21,000) generated a cool heat map. Check it out and tell me what you think. And like usual, you can download the source code from here.
