[Qgis-developer] Suggestion/Question on Snapping

[Randal Hale]

Good morning,

So I'm not a developer by any stretch - but I'm using QGIS for 90% of my 
GIS desktop needs. I have a suggestion/question on snapping. I'm 
currently using QGIS on a large project in the US Virgin Islands. We ran 
into a problem (I hate to call it that) with snapping between two point 
layers. If I set up snapping properly I can add a feature and have it 
snap to the other data layer (point on top of another point). If I bring 
in two existing point layers I can't get them to snap. Example (excuse 
poorly drawn attachment).

  * I had an existing layer of Houses as points.
  * I collected data using a GPS and needed the new GPS point to snap to
    the existing house point. I know I can most likely do this in
    postGIS (and I can do it in openjump).I can also do this in ArcGIS.
  * I move the GPS point towards the house point (within snapping
    tolerance) and it doesn't snap.I tried several different things to
    try to make this work.
  * This also came up in the QGIS class I taught last week and several
    of us tried but couldn't get it to work. All the people in the class
    were arcgis users.


Question (and I know this should head to the user list) am I missing 
something?
If not - Can this functionality be added to help users in the snapping 
realm?

Thank you for all of your excellent work on the 2.0 release.

Randy
