31. Product set-up - set-up Customized Edit Areas - Specifying by lat/lon

Alternatively, you may specify the edit area by giving a (latitude, longitude, dimension) tuple. The dimension is in kilometers and the the system will create a temporary edit area on-the-fly which is a square of the given dimension with the lat/lon as center. An example is shown here. Be sure that your dimension is large enough to include at least on grid point!
