ENVINITFCSMRasterSpatialRef::ConvertMGRSToLonLat

ENVINITFCSMRasterSpatialRef::ConvertMGRSToLonLat

The ConvertMGRSToLonLat method converts Military Grid Reference System (MGRS) coordinates to a set of geographic latitude/longitude coordinates within a NITF Community Sensor Model (CSM) spatial reference.

Example


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

Syntax


ENVINITFCSMRasterSpatialRef.ConvertMGRSToLonLat, MGRS, Lon, Lat [, MODE=integer]

Arguments


MGRS

A string with the MGRS coordinates. You can specify a scalar or a vector of MGRS values.

Lon

A named variable that contains the longitude coordinate

Lat

A named variable that contains the latitude coordinate

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.

MODE

Set this keyword to one of the following integers to determine the format in describing a point on an MGRS grid:

  • 0: Automatic (default)
  • 1: All spheroids are treated the same as WGS-84
  • 2: All spheroids are treated the same as Clarke 1866 or Bessel
  • 10: Automatic; a longitude value of +180 is in Zone 1
  • 11: All spheroids are treated the same as WGS-84; a longitude value of +180 is in Zone 1
  • 12: All spheroids are treated the same as Clarke 1866 or Bessel; a longitude value of +180 is in Zone 1
