I'm using ArcMap Desktop 10.7 for flood analysis using GEOTiff ground elevation rasters.

My hope is to be able to define a grid, for example 10 meters by 10 meters, then recover an average or median elevation value for all raster values in that fall within that cell.

Essentially dividing the resolution of the original resolution into a number of cells I can work with individually.

Ending up with a table of values would be ideal.

I'm expecting it to be a two step process, the first being the definition of the 10 by 10 grid, the second being the calculation of the average or mean elevations for each cell.

Any suggestions appreciated.

Hi Hank

I think I understand. You should then try the

Block Statisticstool that is available in the same toolbox. See How Block Statistics works—Help | ArcGIS Desktop and Block Statistics—Help | ArcGIS Desktop Or you
