[GeoNode-users] Fwd: Raster Upload visualization issues

Tue Jul 4 06:26:52 PDT 2017

Dear Naresh,

you can maybe take a look at those links which may help you clarify better
how the RasterSymbolizer works

http://docs.geotools.org/stable/javadocs/org/geotools/styling/RasterSymbolizer.html

http://docs.geoserver.org/latest/en/user/styling/ysld/reference/symbolizers/raster.html

Unfortunately it really depends on the structure of your data. I will be on
leave those days, for a workshop. If you still are not able to find a
solution, I can try to find some spare time to take a look at your geotiff.
Problem is I really don't know if I will be able to respond in the next
couple of weeks.

Regards,

Alessio Fabiani
