I am trying to calculate/determine the the range of float values associated with the different classes in my thematic raster. For instance, in my thematic raster, I have a class A. If there are 5 cells in my continuous raster data that overlay thematic cells of class A, and these 5 cell have values of 1.2, 3.7, -4.5, 6.23, -0.8, I would like the end result of my calculation to show:</P><PRE class="lia-code-sample line-numbers language-none"><CODE>Class A:&nbsp; Range [-4.5 to 6.23] Class B:&nbsp;&nbsp; .....and so on. </CODE></PRE><P style="margin-bottom: 1em; font-size: 15px; color: #222222; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; background-color: rgba(248, 248, 248, 0.6);">Does anyone know of a way to do this? I've been trying to determine if the raster overlay tools in ArcMap can provide this, but I haven't come across a solution yet.
