title: How to select areas from openstreetmap in django?
body: <p>I would like to build a django webapp. One part of this should allow the user to interactively select geographic areas from a map. The map should come from openstreetmap, and the user should be able to do different kinds of selections:</p>
  
  <ul>
  <li>freehand</li>
  <li>rectangles</li>
  <li>circles</li>
  </ul>
  
  <p>For further processing, the selected area needs to be converted into a shapefile / OGR geometry.</p>
  
  <p>Probably there are already solutions for the individual steps, and I'll have to integrate those. So my question is:</p>
  
  <ul>
  <li>What's the best way to display a OSM map in my django app?</li>
  <li>How do I select the regions?</li>
  <li>How can I convert the selection to an OGR geometry?</li>
  </ul>
  
  <p><em>Note:</em> If I should make this into seperate questions, let me know!</p>
