Description

From a quality image, QLTY2MASK creates a bitmap mask, which can be used as an exclusion mask in color balancing and collection of ground control points (GCP) and tie points (TP).

Parameters

* Required parameter

Parameter descriptions

Input:Quality layer

The name of the GDB-supported file that contains the quality image.

Output:Bitmap layer

The path and name of the PCIDSK file to which to write the bitmap layer in which the exclusion mask is stored.

Details

QLTY2MASK creates a bitmap mask from a quality image.

A quality image is classified to denote land-cover types, water, clouds, and so forth. The image can be created by running the SPECL algorithm or the SPECLASS algorithm. Some products, such as Landsat and Sentinel-2, provide a quality image as a layer.

Classes suitable for neither color balancing nor GCP and TP collection will be converted to a bitmap mask, which can then be used as an exclusion mask in these processes.
