For more information about how this function works, see the Raster Calculator raster function. The referenced raster dataset for the raster object is temporary. To make it permanent, you can call the raster object's save method. The Zonal Statistics as Table geoprocessing tool allows a user to calculate statistics from a raster within zones from a vector layer. For example, one could use a digital elevation model and a state boundaries layer to find the average elevation in each US state. In the ArcToolbox, open Spatial Analyst Tools > Zonal > Zonal Statistics as Table. Input raster or feature zone data: boundary layer. In this example, where the value of the input conditional raster is greater than or equal to 1500, the output value will be 1, and where it is less than 1500, the output value will be 0. # Name: Con_Ex_02.py # Description: Performs a conditional if/else evaluation # on each cell of an input raster.
