I have a topo-bathymetric lidar DEM that I need to construct a CSR for in ArcGIS 10.3. I know how to make colour ramps and personalize them, but I'm wondering if it's possible to make a ramp based on certain elevation values.
I need everything from -20 m to 0 m elevation on the DEM (ie. the bathymetry) to be a colour ramp from dark blue (-20) to light blue (0 m), and then above 0 m (ie. the topography) to be a colour ramp from green through yellow to red. I need the blue to end at 0 m exactly. Any way to do this?
