Parameters:


Name of imagery group for ortho-rectification

Project (location) name
Name of the target project (location)

Name of mapset (default: current search path)
Name of the target mapset

Name of elevation map to use for ortho-rectification

Math expression to convert to real elevation

Unit of the elevation map

DESCRIPTION

i.ortho.elev is used to select or modify the target elevation model for orthorectification of imagery. This elevation model is essential for both the computation of photo-to-target parameters and for the actual orthorectification of imagery group files. The elevation model selected should cover the entire area of the image group to be orthorectified. Optionally, scaled elevation data can be converted to real elevation values specifying a mathematical expression.
