All credit for those beautiful maps go to the http://sitn.ne.ch/ team, I didn't have a play in them. I've cc'd Marc who might be able to share more details as to what he was using exactly (note that those maps predate the actual filter chaining implementation, and used a hack present in 7.0 along with drawing the shaded layers twice). For the water bodies, I suspect it can be done with:
COMPOSITE #first we render normal water color END COMPOSITE COMPFILTER "whiten()" COMPFILTER "blur(5)" COMPOP "soft-light" OPACITY 50 END CLASS STYLE COLOR water-color END END At present filters are not supported on labels (unless they don't go through the labelcache). They could be supported in the longer run if we explicitely had a "labelcache" layer that we could draw into and that we could therefore plug into the compositing chain. regards, thomas On 2 October 2015 at 18:18, Lime, Steve D (MNIT) <steve.l...@state.mn.us> wrote: > Beautiful maps...
