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 properties (Set, Get): INPUT_RASTER, PIXEL_SIZE

Output properties (Get only): OUTPUT_GRIDDEFINITION

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.

This task inherits the following methods from ENVITask:

Properties

This task inherits the following properties from ENVITask:

COMMUTE_ON_DOWNSAMPLE

INPUT_RASTER (required)

Specify a raster with a SPATIALREF that defines the coordinate system to use for the grid definition.

OUTPUT_GRIDDEFINITION

This is a reference to the output ENVIGridDefinition.

PIXEL_SIZE (optional)

Specify a two-element array with the [x,y] pixel size in the same units as the raster.
