Flying camera squad helps update maps.
Ordnance Survey has taken to the skies in the most intensive programme of aerial photography ever undertaken in Britain. The photographs will be used to revise OS's largest scale maps up to a scale of 1:1250. "On a good day, they could be taking 1000 photos from the air," explains Philip Round, senior press officer at OS.
The photographing will continue intensively all summer--in all 65,000 pictures will be snapped this year. The programme is part of a 42 million [pounds sterling] government investment aimed at improving the country's mapping services. "There has been some concern in rural areas that maps haven't been updated. A reason is because there's less change than in urban areas," explains Round. "But now rural areas will be updated too."
Back on solid ground in OS's Southampton office, the photographs will be overlaid on highly detailed computer maps. Operators will be able to see any changes that have occurred and make the necessary alterations. The photos will be so sharp that even features as small as car sunroofs will show up.
