[Geoserver-users] Tile edges issue

Hi everyone, I am experiencing issues where I try to generate a heatmap using a style in which the tile edges show. It is as though the surrounding tiles do not know to render the outer parts of the heatmap. I used the style found here: https://docs.geoserver.org/latest/en/user/styling/sld/extensions/rendering-transform.html

The style in use is the one that renders points into the heatmap. I tried searching for solutions but I don’t know if I am not using the correct terminology.

Anyone have any ideas or suggestions?

Thanks for your help

This is a well known problem and there is nothing that GeoServer can do about it. See https://gis.stackexchange.com/questions/245379/adjust-geoserver-geotools-heatmap-code-to-show-it-as-tiled-wms for a longer explanation

Simple solution is to not use tiles, better solution is to pre compute the heat map and server the result up as a layer.
