title: geolocation and a floorplan - javascript marauders map
body: <p>If someone gave you point A(lat,lon) and point B(lat,lon) on a floor plan image, and you have the width and height of the floorplan image, can you then use geolocation to track where they are as they walk around?  </p>
  
  <p>Are there any projects you know of that attempt to solve this?</p>
