Reverse geocoding will be implemented for the new version of the GPSSync plugin as part of GSOC by Gabriel Voicu, mentored by Michael G. Hansen.

Short description

The idea of reverse geocoding is that when the coordinates on earth of an image are known, the application retrieves the associated human readable location: City, street, country, etc. and stores this information in the image. The location names can be stored in the images as new tags, allowing the user to easily search for all pictures he took in a country, city or even street.

Where is the code?

  • gsoc-geocoding: General place for experiments and small code snippets.
  • GPSSync2: New version of the GPSSync plugin.
  • WorldMapWidget2: Widget to display the location of images on both Google Maps and Marble. Required by GPSSync2.
