OpenHeatMap is a service designed to make it easy for non-specialists to create maps communicating information. It transforms data from a traditional data source such as a spreadsheet into an interactive animated view of a particular area. You can then share that map online, a bit like YouTube for geographic visualizations.

For developers, it’s a JQuery plugin that makes it easy to create a completely open-source mapping component on any web page, using either Flash or HTML5’s Canvas element under the hood depending on the platform and preferences.

erything but the core rendering is designed to be controlled by Javascript within the hosting page. You can get a list of the event hooks and callable functions at the Component API calls page.

The website backend and map processing tools are built using PHP. The overall control of the component is handled through Javascript, and there’s two alternative rendering engines; a Flash SWF file written in Flex and a pure Javascript implementation using Canvas on modern browsers.
