The Mask Polygons operation can be directly executed by typing the following expression on the command line of the Main window:
|
OUTMAP |
= |
PolygonMapMask(Input PolygonMap,"mask") |
where:
|
OUTMAP |
is the name of your output polygon map. |
|
PolygonMapMask |
is the command to start the Mask Polygon operation. |
|
InputPolygonMap |
is the name of the input polygon map. |
|
"mask" |
are the (multiple) search strings to find the classes, IDs or values in the input map that you want to copy into the output map; on the command line, the total mask needs to be surrounded by double quotes. |
When the definition symbol = is used, a dependent output map is created; when the assignment symbol := is used, the dependency link is immediately broken after the output map has been calculated.
