Attribute map of raster map
Algorithm
The program scans the raster map line by line, starting with the first (left) pixel in the first line until the last (right) pixel in the last line.
Each pixel is copied to the output map:
- each class name or ID in the input map is replaced with the attribute value that belongs to this class or ID as found in the attribute table.
Undefined values are assigned to an output pixel:
- if the pixel in the input map is undefined, or
- if the class name, ID, or value in the selected attribute column is undefined.
