We would like to build a simple web map application that displays raster data (e.g. a digital surface model) and symbolizes values (e.g. height) using a color ramp.
Is it possible to have the user manipulate the symbolization, maybe even allow to perform a classification?
For example like this: http://maps.nrel.gov/biomass - only that we would like to additionally change the classification on the client side.
I am aware of WCS and read about GDAL in this answer, but it did not help much.
Can anyone point me to some actual examples doing raster manipulation?
