Zonal statistics
Why use zonal statistics?
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).
The graphics below show an example of the inputs
and outputs from the Zonal Statistics function.
The variety of vegetation species per elevation zone
is displayed in the output table and chart. The most
variety of species occurs at elevation levels of around
2,500 meters.
