I have a shapefile (Multiline Shape). The user clicks on the line at the point where they want to split the line. I need to be able to:
1. If the click point is within a tolerance of a vertice, split the line at the vertice
2. If the click point in not within a tolerance, split the line at the vertice.
To complicate things, my shapefile is in lat,lng and I have added in the google Map overlay, thus I have projected the shapefile to match google. I need to take this into account when splitting the line.
The only example I could find uses the WorldMapKitWms, which we do not have, and at present are not considering purchasing. Any help with this would be greatly appreciated.
