ENVICoordSys::ConvertMapToMap

ENVICoordSys::ConvertMapToMap

The ConvertMapToMap method converts a set of map coordinates (x-eastings, y-northings) for a vector file in one coordinate system to the same geographic location in another coordinate system.

Syntax


ENVICoordSys.ConvertMapToMap, Map1X, Map1Y, Map2X, Map2Y, CoordSys2

Arguments


Map1X

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

Map2X

A named variable containing the x-coordinate in the second spatial reference

Map2Y

A named variable containing the y-coordinate in the second spatial reference

CoordSys2

A reference to a CoordSys 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.
