Hi, I like to calculate the mean raster value of areas in a raster image. The boundaries of the areas are defined by polygons in a separate shapefile. The result of the mean value should record in an attribute column within the shapefile. Finally, I like to convert this mean value for every polygon area by a simple equation and record the result once again in a separate attribute column within the shapefile. I hope my problem is formulated understandably!
I would recommend of the zonal statistics or zonal statistics as a table. They should create the desired output. With the Zonal Statistics as a Table, you will have to join the table back to the original shapefile.
