The Historic England Archive holds the largest public archive of aerial photographs in England, organised as two distinct collections – oblique and vertical – each acquired from different sources. More than 680,000 oblique (taken at an angle to the ground) aerial photographs of locations throughout England are available on open access in the Historic England Archive search rooms. The archive also holds more than two million vertical (bird's-eye view) aerial photographs, covering the whole of England, including near-complete coverage taken by the RAF in 1946–48. These are available via a search request from the Archive Services Team. The 'Britain from Above' project, funded by the Heritage Lottery Fund, completed digitisation and cataloguing of 95,000 of the Aerofilms aerial image negatives from 1919 to 1953 and put them online.
