ConvertGeographicToMapCoordinates Task
This task converts geographic (latitude/longitude) coordinates to map (northings/eastings) 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('ConvertGeographicToMapCoordinates')
; Define inputs
Task.INPUT_COORDINATE = [-105.20618986,39.99754473]
Task.SPATIAL_REFERENCE = Raster.SPATIALREF
; Run the task
Task.Execute
Print, Task.OUTPUT_COORDINATE
Result:
482398.87 4427504.9
Syntax
Result = ENVITask('ConvertGeographicToMapCoordinates')
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.
