Heatmap Generation Library for PHP

Question

I want to generate heatmap images as overlay for Google Maps. I am searching for a PHP library which can take multiple dimensions into account when generating the image. Let's say i have 2 dimensions: density and quality. How could a heatmap be generated from this input?

Answer 1

Use fusionTable, refer to here for some sample PHP code.

Answer 2

If you want to generate heatmap layers over google maps you probably want to check out heatmap.js too, it's licensed under the MIT license. It works with the HTML5 Canvas element and JavaScript.
