ENVINITFCSMRasterSpatialRef::ConvertLonLatToLonLat
The ConvertLonLatToLonLat method converts a set of geographic latitude/longitude coordinates in a NITF Community Sensor Model (CSM) spatial reference to the same location in another NITF CSM spatial reference. The associated ENVIRasters' metadata must include a coordinate system string.
Example
See the example for ENVIStandardRasterSpatialRef::ConvertLonLatToLonLat. The use of this method is the same except that it is for use with a NITF CSM dataset.
Syntax
ENVINITFCSMRasterSpatialRef.ConvertLonLatToLonLat, Lon1, Lat1, Lon2, Lat2, SpatialRef2
Arguments
Lon1
The longitude coordinate in the first spatial reference. You can specify a scalar or a vector of longitude values; if it is a vector, the Lat1 argument should also be a vector with the same number of elements:
Lon1 = [-123.58, -134.64]
Lat1 = [48.23, 49.56]
Lat1
The latitude coordinate in the first spatial reference
Lon2
A named variable that contains the longitude coordinate in the second spatial reference
Lat2
A named variable that contains the latitude coordinate in the second spatial reference
SpatialRef2
A reference to an ENVIRasterSpatialRefRPC object in the second 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.
