Updating urban maps with analytically rectified Small Format Aerial Photographs

Abstract

Small Format Aerial Photography (SFAP) is a new emerging art of acquiring photogrammetric data with metric and non-metric cameras. SFAP with format size normally less than 55×55 mm, possesses the potential of both compiling new maps and updating existing planimetric maps of small areas. Organisations dealing with urban and other large-scale mapping, may be benefited greatly by the use of such data. In the present study, investigations are carried out to update an urban map on scale 1∶10,000 using analytically rectified SFAP from non-metric camera. Results are encouraging and presented in this paper.
