Hi johndiss, thanks for the quick reply!..:)
your hint helped me to found the start and end positions. Could you give me more help in finding the exact location of the km-sections?
The first problem is that with the GetBoundingBox ( layer.DataSource.ExecuteIntersectionQuery(ClickPnt.GetBoundingBox(), featdset); ) I get result even from 100 pixel distance from the line. I don't understand why..?
The second problem is that unfortunately one section is composed of usually 4 to (even) 30 pieces/nodes (polyline). Those make a semi-curve. How can I position the calculated km-point on exactly the line? Because if I counted the location based on only the
start and end points, it obviously would be somewhere out of the line...
Is SharpMap capable of doing such things?
Ps.: where can I find more info about nts and where can I download it from? (and the geoapi.dll?) thanks!
