AW: Re: Fwd: [Qgis-user] QGIS "Near"

[Ziegler Stefan]

Hi Zoran
 
I had some time left, took all my code snippets and also the one from
Carson. Please try the plugin "Nearest" that should cover your example

      which "Snaps to segment or vertex within given tolerance." seem
      like
      what you're looking for? I came across it while trying to get
      Quantum
      Navigator working recently...seemed relative, but I'm no expert!
      
      


   This is similar to the mentioned solution with selecting by radius,
   or changing the tolerance of ID tool. Close, but no cigar. Since this
   is not very urgent, I've decided to continue pursuing that outlined
   solution Carson gave, and write a plugin i Python based on that.
   Since I actually never used Python before, it may take a while, but
   hey, I get to learn sth. new :-).
   I never got the word back from Carson, has he developed anything
   along these lines, but I have to presume he didn't...
   Anyone interested in joning me, or even earning some money, is still
   invited to jump on board. My GIS implementation project is well on
   the way, and it seems there'll even be some money involved :-).

      It sort of is, but not completely. Identify will ID all the
      features within
      certain radios (percentage of extent), but it will ID _all_ of the
      features
      within this radius. I only need the nearest, no matter how far
      away... Let
      us say it is, for simplicity, within current extent.

      Look above. This could be useful, but it is not the functionality
      I'm
      currently looking after.

      Yup, these are great, but they all select _multiple_ features
      within radius,
      rectangle, etc.
