Unique ID

The Unique ID operation can be used to assign unique identifiers to all elements in a segment, polygon or point map. The output map contains the same geographic information as the input map, but each point, segment or polygon will have a unique ID.

Furthermore, an attribute table is created for the output map. The table contains a column with the original classes, IDs or values of the input map; the areas of individual output polygons; the lengths of individual output segments.
