NAME

i.ortho.elev - Select or modify the target elevation model.

KEYWORDS

imagery, orthorectify

SYNOPSIS

i.ortho.elev
i.ortho.elev --help
i.ortho.elev [-p] group=name [project=name] [mapset=name] [elevation=name] [math_expression=string] [units=string] [null_value=string] [--help] [--verbose] [--quiet] [--ui]

Flags:

-p: Print currently selected elevation map and exit
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

group=name [required]: Name of imagery group for ortho-rectification
project=name: Project (location) name
Name of the target project (location)
mapset=name: Name of mapset (default: current search path)
Name of the target mapset
elevation=name: Name of elevation map to use for ortho-rectification
math_expression=string: Math expression to convert to real elevation
units=string: Unit of the elevation map
Options: miles, feet, meters, kilometers, acres, hectares
null_value=string: No data value

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.
