ConvertMapToGeographicCoordinates Task

This task converts map (northings/eastings) coordinates to geographic (latitude/longitude) coordinates.

Example

; Start the application

e = ENVI(/HEADLESS)

; Open an input file

File = Filepath('qb_boulder_msi', Subdir=['data'], $

  Root_Dir=e.Root_Dir)

Raster = e.OpenRaster(File)

; Get the task from the catalog of ENVITasks

Task = ENVITask('ConvertMapToGeographicCoordinates')

; Define inputs

Task.INPUT_COORDINATE = [482399.0584,4427505.0643]

Task.SPATIAL_REFERENCE = Raster.SPATIALREF

; Run the task

Task.Execute

Print, Task.OUTPUT_COORDINATE

Result:

-105.20619       39.997544

Syntax

Result = ENVITask('ConvertMapToGeographicCoordinates')

Input parameters (Set, Get): INPUT_COORDINATE, SPATIAL_REFERENCE

Output parameters (Get only): OUTPUT_COORDINATE

Parameters marked as "Set" are those that you can set to specific values. You can also retrieve their current values any time. Parameters marked as "Get" are those whose values you can retrieve but not set.

Input Parameters

INPUT_COORDINATE (required)

Specify an array of map coordinates in [x,y] format.

SPATIAL_REFERENCE (required)

Specify an ENVIStandardRasterSpatialRef object indicating the spatial reference of the input coordinates.

Output Parameters

OUTPUT_COORDINATE

An array of geographic coordinates in [longitude, latitude] format.
