IsoLink4

Function IsoLink4(filename: string; nodenum: integer): integer;

IsoLink4 calculates links, which shows which center is the nearest on a street network.

The functionality is similar to IsoPoly4, but the result is a polyline theme instead of a polygon theme and the polylines are dynamically segmented to show the exact position where it changes, which center is the nearest.

The result is saved to filename, which should include path and filename, but exclude extension.

Nodenum specifies the number of nodes entered into the standard nodelist (centers).

The output format is determined by property GISformat.

Possible error codes: -10 -30 -40 -41 -46
