I'm trying to find the source code for the GeoServer Heatmap rendering transformation. I can't find anything relevant in the GeoServer GitHub repo.

This page in the developer guide includes a code snippet from the transformation but when I search for "public class HeatmapProcess implements GeoServerProcess" that page in the developer guide is the only result.

I'd like to learn how the transformation produces grid cell values as there's no documentation on the internal logic.

  • firefly-orange, can you give a example for use heatmap? Please. Thank you – Giancarlo Bruno Honores Feb 23 '18 at 17:40

    @GiancarloBrunoHonores please don't hijack questions. Please ask a separate question and elaborate - A LOT! – firefly-orange Feb 25 '18 at 22:17

GeoServer uses the heatmap process from GeoTools. Here is the link.
