Raster to polygons

Command line

The Raster to polygons operation can be directly executed by typing the following expression on the command line of the Main window:

  

OUTMAP

=

PolygonMapFromRas(InputRasterMapName)

OUTMAP

=

PolygonMapFromRas(InputRasterMapName, 8|4)

OUTMAP

=

PolygonMapFromRas(InputRasterMapName, 8|4, smooth|nosmooth)

where:

OUTMAP

is the name of your output polygon map.

PolygonMapFromRas

is the command to start the Raster to Polygons operation.

InputRasterMapName

is the name of your input raster map.

8|4

is an optional parameter to indicate whether to construct 8-connected 4-connected areas (either 8 or 4) from which polygons should be extracted; when this parameter is not specified, 8-connected areas will be used.

smooth|nosmooth

is an optional parameter to indicate whether the boundaries of the output polygons should be smoothed or not (type either smooth or nosmooth); when this parameter is not specified, boundaries will be smoothed.

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.
