Spot Image, a leading provider of satellite imagery, are making a fantastic offer. Spot Image are teaming up with GeoNames to help improve the availability of free geographical data and offer high resolution 2.5m satellite imagery for automatic feature extraction.
Features that we think can be extracted from 2.5m imagery are city contours, airports, streets, shore lines, lakes, rivers and others. We believe this is a fantastic opportunity for researchers and student-works to find algorithms for feature identification and extraction. Drop me a line for more details if you are doing research in this area and would like to work on this challenging task.

The data extracted from satellite imagery will be made available through GeoNames. Up to now GeoNames was exclusively focusing on point data due to the lack of good and free vector data. The extracted features will allow us to provide vector data and we will be able to include shapes of cities and other features into the GeoNames database. It will be a gigantic step forward for the availability, quality and coverage of free geographical data on global scale.
Spot Image, based in Toulouse (France), are providing satellite imagery to GoogleEarth and they are selling images to professional and private users.
