Zonal Overlay Statistics

Zonal functions take a value raster as input and calculate for each cell some function or statistic using the value for that cell and all cells belonging to the same zone.

The zonal functions are grouped by how the zones are specified, either by a single input value raster or by a second zone raster.

Zonal functions in which the zones are defined by a single input value raster either calculate statistics or quantify the characteristics of the geometry of the input zones. Zonal functions in which the zones are defined by a second zone raster either calculate statistics or fill specified zones with values from the input value raster.

You might calculate the mean elevation for each forest zone or the number of accidents along each of the roads in a town. Alternatively, you might want to know how many different types of vegetation there are in each elevation zone (variety).

Available Zonal Overlay Statistics tools include:
