Workflow

  1. Get image to be referenced about a region on earth; e.g. a floor plan from a building ('building map').
  2. Start Google Earth, create "New overlay..." and georeference image.
  3. In Google Earth export overlay as KML (not KMZ) "Save As...".
  4. Start WorldFileTool
    1. Choose "Open KML..." (which includes already overlay title, image name, bbox)
    2. (optional) or 1. open image file (e.g. jpg), take worldfile (e.g .jpw)
    3. add metadata in GUI: floor (-99..99) and priority (0=nil=>unknown,1..100), map type (<background>1<background>) change title.
  5. using WorldFileTool do either...
    1. "Save KML" again
    2. (optional) Export world file
    3. (optional) Generate 'background map' (includes KML and image) (internet access required).
  6. Use georeferenced image in your GIS viewer (e.g. IndoorWPS), map server or GIS.

There exist alternatives to georeference an image: See GISpunkt Wiki (german) and freegeographytools.com.
