This looks cool Gagan.
I think something like this would make a great addition to our editing
tools. We'd need to have some discussion about where to put the linear
referencing functions, as I know there is already concern about the size
of our geometry classes.
I'm seeing some unhandled errors about an object not having a distanceTo
method. If you could address these and create a patch, opening a ticket
would be a good next step.

Hi,
In one of my project there is requirement of tracing of feature along
another feature while drawing a new feature. I have written control for this
(Trace). There are are some issues for that i need suggestion.
Here is the working example -
http://geometricnet.sourceforge.net/examples/trace.html
code for trace control -
http://geometricnet.svn.sourceforge.net/viewvc/geometricnet/tags/rev192/lib/GeometricNet/Control/Trace.js
- for the Trace control I am taking input as Snapping object, instead of
extending the Snapping class, what could be the best way.
- here I require some Linear Referencing functions so written those
functions. Are LRS functions available in OpenLayers
(http://geometricnet.svn.sourceforge.net/viewvc/geometricnet/tags/rev192/lib/GeometricNet/Util.js)
- I have made slight modification in Snapping control - snap event returns
the snapped Feature also. Here is the diff (
http://geometricnet.svn.sourceforge.net/viewvc/geometricnet/tags/rev192/lib/OpenLayers.patch?revision=193&view=markup)
- Is this control can be part of the OpenLayers? In case yes, how can I
contribute it.
Regards,
Gagan
