I have a lidar DEM model of the Houston area floodplain with polygons representing areas protected by levees. I would like analyze the elevation within each levee by sampling the elevation values within the polygons and representing them as a histogram or frequency plot. Ideally, the x axis would be binned elevation and the y axis would be the frequency (count).
I've tried the Sample Tool from the spatial analyst toolset, but instead of obtaining the elevation values, I seem to be getting a number between 1 and 256 (...the display value?)
