4. Calculate Zonal Statistics
Description
This tool calculates zonal statistics for all rasters referenced by the reference source raster (for example, if a ponded depth raster is selected, then the statistics will be calculated for all the ponded depth rasters in the folder where the reference raster resides based on the reference raster prefix) and zones defined in the input zone polygon feature class. The results are stored in the output zonal statistics table referenced by the zone and raster names (index).
Usage
