Select a name (Max_Elev) and location for the Output raster generated.The Zone field is a field in the polygon feature class that contains a unique value for each polygon feature, such as OBJECTID.The Input raster or feature zone data is the polygon feature class.For example purposes, name this raster 'Max_Elev.' The input and output parameters are as follows:
This generates a new raster that changes all the cell values in each polygon feature to the value of the highest elevation within that polygon feature. Identify the value of the highest elevation within each polygon feature using the Zonal Statistics tool: Open ArcMap and navigate to ArcToolbox > Spatial Analyst Tools > Zonal > Zonal Statistics.Note:Ī polygon feature class, a DEM, and the Spatial Analyst extension are required for this procedure. The three general steps of the procedure are to identify the maximum elevation values within each polygon, identify which specific cells in the DEM correspond to the maximum values, and then convert those cells to a point feature class. In this example, highest elevations are used, but method this also works for lowest elevations. This procedure describes a basic workflow that generates a point feature class of the highest point within each polygon feature. Using a Digital Elevation Model (DEM) raster and the Spatial Analyst extension, the location of the highest or lowest elevation can be identified for polygon features of interest. How To: Create points representing the highest or lowest elevations within polygon features Summary
