Isle of Dogs, London, historical aerial photographic mosaic taken between 1939 and 1952. Between 1939 - 1942 Hitler's Luftwaffe secretly photographed large areas of Great Britain and Ireland for target reconnaissance. From 1946 until 1952 the Royal Air Force began detailed aerial surveys for planning and reconstruction work following the Second World War. Both sources have been used to create these historical aerial maps. Present day images of the same towns and cities reveal extensive changes to roads, buildings and public spaces. See image C016/9934 for the same aerial photograph taken in 2011.
