Trace Along Featue in OpenLayers
The requirement for vector editing at web browser is increasing. Future would not be a web based GIS editor package rather plugable tools for vector editing in the web site. In this regards OpenLayers serve a good platform as a library. I have developed a tool for tracing the feature along existing feature. Here is the working example. I am looking for the feedback on this control regarding the enhancement as well as any bug. Want to test trace control, check the patch for openlayers.
There is one more functionality I would like to add in this control, trace polygon in another direction by pressing shift/ctrl. If any more suggestion please let me know.
