My idea was to use simplify as a geometry transformation in my SLD to improve performance at certain scales where OSM data is just too heavy and all the normal tricks for performance just don’t cut it.
Reading the function reference it says: “If a function is described in the Capabilities document but is not in this reference, then it might mean that the function cannot be used for filtering, or that it is new and has not been documented. Ask for details on the user mailing list.”
How is the “approved” function list controlled? Is there a way to change it by configuration?
By the way I’m using PostGIS with “on the fly simplification” enabled but still the queries do NOT use ST_Simplify. It seems like this would be a better solution. Where can I learn more about how this feature works?
Thanks,
Jason
