I remember a database rules based solution I saw demonstrated on the old mapguide 6.5 website. Those application demos aren't available any longer but it is at least a thought that it could be done through rules based snapping.

The closest to an actual implementation I have seen is the MapBender project. Regards, Kenneth, GEOGRAF A/S Maksim Sestic skrev: It's relatively easy to do. Here're the basic steps: 1) Make a Buffer around a point (buffer size = treshold) 2) Find LineStrings intersecting a Buffer 3) If no LineStrings were found, then return original point (or whatever) 4) Enumerate each LineString vertex to see which one is closest to the point (distance comparer) 5) Return closest LineString vertex as a "snap" point Regards, Maksim Sestic Wind wrote: hello everyone: Has anyone done any snapping point to line in mapguide enterprise? ---------- Forwarded message ---------- From: Wind <mailto:[EMAIL PROTECTED]> <[EMAIL PROTECTED]> Date: Dec 18, 2007 11:38 AM Subject: Re: [mapguide-users] Digitizing demo To: [email protected] hello everyone: Has anyone done any snapping point to line in mapguide enterprise?

Does anybody have digitizing tools working in a demo that I can view? Is anybody interested in developing the tools to make them really efficient? We need tools that give added functionality for editing, creating new points by adding a distance and a bearing from one point to the next, creating shapefiles, downloading shapefiles, snapping points to lines and more.... thanks -- View this message in context: http://www.nabble.com/Digitizing-demo-tp4127680s16610p14377506.html Sent from the MapGuide Users mailing list archive at Nabble.com. _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users
