I have GIS data in a PostGIS data base and would like to generate a density map and display them on a Leaflet/Google Maps.

Question: What is the recommended/typical method for doing so, without transferring ALL (millions) the data points within the map's viewpoint to the Leaflet/Gmaps map? No user intervention (ie. Import data into ArcGIS to generate the map) should be required unless automation is possible via CLI etc.

Currently using Postgresql/PostGIS as the spatial database and Leaflet on the browser.

You can try using middleware such as Geoserver which can generate heatmaps for you: http://docs.geoserver.org/stable/en/user/styling/sld-extensions/rendering-transform.html#heatmap-generation

  • Geoserver looks awesome! Any idea how we can get the value at a specific point on the heatmap? (eg: in the screenshot in original post)
