Declassified Military Aerial Images Map
The Royal Commission on the Ancient and Historical Monument of Scotland are busy mapping declassified military aerial photographs on Google Maps.
The Aerial Reconnaissance Archives have millions of military reconnaissance images of locations throughout the world declassified by the UK Ministry of Defence. The archives range from Second World War Allied and German Luftwaffe reconnaissance photographs to Cold War imagery.
To date RCAHMS have mapped reconnaissance photographs in Belgium, Croatia, the Czech Republic, Denmark, France, Germany, Italy, the Netherlands and Poland. Using Google Maps to display the photographs means that users can compare the present day satellite view of locations with reconnaissance images from the past (mostly from World War II).
