SubsetLabelRaster Task

This task builds a new deep learning label raster using a subset of existing labels in another raster. This is useful for removing confusing classes or reusing already-labeled data for a new project.

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('SubsetLabelRaster')

; Define inputs

Task.INPUT_RASTER = Raster

; Run the task

Task.Execute

; Add the output to the Data Manager

e.Data.Add, Task.OUTPUT_RASTER

; Display the result

View = e.GetView()

Layer = View.CreateLayer(Task.OUTPUT_RASTER)

Layer.QUICK_STRETCH = 'linear'

Syntax

Result = ENVITask('SubsetLabelRaster')

Input parameters (Set, Get): INPUT_RASTER, OUTPUT_LABELS, OUTPUT_RASTER_URI

Output parameters (Get only): OUTPUT_RASTER

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.

Input Parameters

INPUT_RASTER (required)

Specify the input raster.

OUTPUT_LABELS (required)

Specify a subset of existing labels from the INPUT_RASTER that will be applied to the OUTPUT_RASTER.

OUTPUT_RASTER_URI (optional)

Specify a string with the fully qualified filename and path of the associated OUTPUT_RASTER. If you do not specify this property, or set it to an exclamation symbol (!), a temporary file will be created.

Output Parameters

OUTPUT_RASTER

This is a reference to the output raster of filetype ENVI and byte data type.
