They can be used both, but the specific examples you cite won't work together:
- A rendering transformation replaces the source data the style is used against, you call the SLD on top of a set of points, and, say, "heatmap" turns it into a raster (so your style must be for the raster) - A geometry transformation takes a single geometry from a feature and applies a function to get some other geometry (e.g., from line to centroid of the line), if there is a rendering transformation it will be applied on the results of the transformation Long story short, they should work together, as long as the RT generates vector data, and the geometry transformation is meant to work on top of the results of the RT (not its inputs, it will never see them): - pointstacker -> centroid(line) works but the centroid is applied on the points extracted by the point stacker, doing nothing (the centroid of a point, is a point) - heatmap -> centroid(line) does not work, because centroid cannot be applied on a raster dataset Hope this helps Cheers Andrea On Wed, Jul 1, 2020 at 12:56 PM Alexandre Gacon <[email protected]> wrote: > Hi every one, > > Is it possible to mix rendering transformation like PointStacker or > Heatmap with geometry transformation like centroid(line) in styling? > > Or should I create a view computing the geometric transformation first? > (My data are in a Postgis database). > > Regards > > -- > Alexandre Gacon > _______________________________________________ > Geoserver-users mailing list > > Please make sure you read the following two resources before posting to > this list: > - Earning your support instead of buying it, but Ian Turton: > http://www.ianturton.com/talks/foss4g.html#/ > - The GeoServer user list posting guidelines: > http://geoserver.org/comm/userlist-guidelines.html > > If you want to request a feature or an improvement, also see this: > https://github.com/geoserver/geoserver/wiki/Successfully-requesting-and-integrating-new-features-and-improvements-in-GeoServer > > > [email protected] > https://lists.sourceforge.net/lists/listinfo/geoserver-users > -- Regards, Andrea Aime == GeoServer Professional Services from the experts!
