I have seen several discussions about zonal statistics and similar processes for summarizing rasters by polygons, however I have a question that I can't seem to find an answer to. Most of these past questions ask about summarizing 1 raster at a time.
Currently I have about 60 separate raster files (ascii but can be converted to .tif if needed) and polygon shapefile counties for several states. I would like to summarize the 60 rasters by county. I imagine the attribute table will have each county as a row and the mean of each raster as columns.
Correct me if I'm wrong, but it seems the zonal statistics tool only does 1 raster at a time and batch processing wouldn't fix that. Also, I believe the zonal statistics tool output is a raster, correct? I would like the results of each raster to be added to the polygon shapefile attribute table.
Is there another way to do this? I am open to python or R solutions.
