How do I assign average raster values to polygons within a shapefile

DavisTolman

I have a raster file (elevation) and a shape file (neighborhood polygons). I would like to sample the raster for each polygon and assign the average raster value to its' respective polygon. Ideally I would add a new column with the average elevation for each row in the shape file.

If you have access to Spatial Analyst, one possibility is to use Zonal Statistics, with the statistics_type (optional) of Mean:

ArcGIS Help (10.2, 10.2.1, and 10.2.2) Zonal Statistics

Hi Amy,

I'm sorry, I don't recall and unfortunately I can't seem to find my notes on that project. I was likely helping a student and they ended up doing something else. If you find an answer though, please post it here!
