To create a distance map or a travel time map, the distance calculation can be directly executed by typing one of the following expressions on the command line of the Main window:
|
OUTMAP |
= |
MapDistance(SourceMap) |
|
OUTMAP |
= |
MapDistance(SourceMap,WeightMap) |
where:
|
OUTMAP |
is the name of your output raster distance map. |
|
MapDistance |
is the command to start the Distance calculation operation. |
|
SourceMap |
is the name of the source map; the source map can be a map with a class, ID, or value domain. |
|
WeightMap |
is the name of the optional weight map; the weight map should be a map with a value domain. |
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.
