ENVINITFCSMRasterSpatialRef::ConvertMapToMap

ENVINITFCSMRasterSpatialRef::ConvertMapToMap

The ConvertMapToMap method converts a set of map coordinates (x-eastings, y-northings) in a NITF Community Sensor Model (CSM) spatial reference to the same location in a second NITF CSM spatial reference. This method requires two coordinate systems.

Example


See the example for ENVIStandardRasterSpatialRef::ConvertMapToMap. The use of this method is the same except that it is for use with a NITF CSM dataset.

Syntax


ENVINITFCSMRasterSpatialRef.ConvertMapToMap, Map1X, Map1Y, Map2X, Map2Y, SpatialRef2

Arguments


Map1X

The map x-coordinate (easting) in the first spatial reference. You can specify a scalar or a vector of Map1X values; if it is a vector, the Map1Y argument should also be a vector with the same number of elements:

Map1X = [481874.4000D, 482260.8000D]
Map1Y = [4428160.8000D, 4427992.8000D]

Map1Y

The map y-coordinate (northing) in the first spatial reference

Map2X

A named variable that will contain the map x-coordinate in the second spatial reference

Map2Y

A named variable that will contain the map y-coordinate in the second spatial reference

SpatialRef2

A reference to an ENVIStandardRasterSpatialRef object that is in a different spatial reference.

Keywords


ERROR

Set this keyword to a named variable that will contain any error message issued during execution of this routine. If no error occurs, the ERROR variable will be set to a null string (''). If an error occurs and the routine is a function, then the function result will be undefined.

When this keyword is not set and an error occurs, ENVI returns to the caller and execution halts. In this case, the error message is contained within !ERROR_STATE and can be caught using IDL's CATCH routine. See IDL Help for more information on !ERROR_STATE and CATCH.

See Manage Errors for more information on error handling in ENVI programming.
