I have a bunch of polygons that are overlayed on top of some raster data (ENVI Tasseled Cap Bands). I want to determine what the average value of wetness or greenness in each polygon. Can anyone point me in the right direction?
Zonal Statistics as Table is a good starting point. Your polygons will be the zone features, and run it on the greenness and wetness bands separately. The tool only takes 1 band rasters, so you can't input your multiband dataset. One of the stats returned to you is Mean value per zone.

The question was about AREA-WEIGHTED mean. Zonal Stats does NOT do that, as I understand it. Is that correct?
