BuildGridDefinitionFromRaster Task
This task returns a grid definition, which provides the information needed to georeference rasters to a common coordinate system.
Example
; Start the application
e = ENVI()
; 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('BuildGridDefinitionFromRaster')
; Define inputs
Task.INPUT_RASTER = Raster
; Run the task
Task.Execute
; Print the ENVIGridDefinition
Print, Task.OUTPUT_GRIDDEFINITION, /IMPLIED_PRINT
Syntax
Result = ENVITask('BuildGridDefinitionFromRaster')
Input parameters (Set, Get): INPUT_RASTER, PIXEL_SIZE
Output parameters (Get only): OUTPUT_GRIDDEFINITION
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_RASTER (required)
Specify a raster with a SPATIALREF that defines the coordinate system to use for the grid definition.
PIXEL_SIZE (optional)
Specify a two-element array with the [x,y] pixel size in the same units as the raster.
Output Parameters
OUTPUT_GRIDDEFINITION
This is a reference to the output ENVIGridDefinition.
