IsoLink2

Function IsoLink2(filename: string; nodenum: integer): integer;

IsoLink2 calculates isocost links, which shows how far it is possible to go within a specified amount of cost from one or more nodes.

Use procedure StepsClear and StepsAdd to add a list of the actual isochrones generated.

The output is similar to IsoPoly2, but the result is a polyline theme instead of a polygon theme and the polylines are dynamically segmented to show the exact position of the steps.

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 NodeListSet.

The output format is determined by property GISformat.

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