If this can be done could anyone point me in direction of an example please?
I've gone through various links etc. but not finding anything so far that
relates this to a raster DEM.
I have a 32bit DEM for Ireland and use the below style as its colour ramp which
all seems to work fine on a global scale.
There's 255 ColorMap levels but only start and end shown below.
The issue is that viewing the DEM globally is fine but locally I think more
detail can be discerned if a dynamic style was possible.
For example looking at the global DEM the highest point should be red and the
lowest blue and everything else in between should slot into a ramp level.
But when we query this WMS with an extent constraint is it possible to set a
dynamic style such that red still defines the highest point in the region and
blue the lowest with the rest following a ramp?
