OpenHeatmap is a highly customizable mapping resource that comes in 2 flavors:

  • web-based free service:  creating maps that can be shared easily (for end-users)
  • jQuery plugin: more flexible choice with using either Flash or HTML5’s Canvas element to create maps (for developers).

OpenHeatmap

It makes generating thematic maps possible by using the OSM XML file format (OpenStreetMap).

And, if wanted, density/blob based traditional heatmaps can be created too.

The plugin has a feature-rich API and every aspect of the maps can be controlled with JavaScript (like adding pop-ups, allowing zoom, changing colors and sizes, etc.).
