ConvertMapToGeographicCoordinates

ENVIConvertMapToGeographicCoordinatesTask

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 properties (Set, Get): INPUT_COORDINATE, SPATIAL_REFERENCE

Output properties (Get only): OUTPUT_COORDINATE

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