GPS assisted helicopter photogrammetry for highway profiling
Joy, Christopher Iain Harold (1998) GPS assisted helicopter photogrammetry for highway profiling. PhD thesis, University of Nottingham.
Roads are an integral part of today's lifestyle. Indeed, a modern and efficient economy requires a satisfactory road network. The road network in the United Kingdom faces ever-increasing demands with 94% of passenger travel and 92% of freight transport undertaken by road. Maintenance of the network is essential. Prior to the commencement of any maintenance scheme, an accurate highway profile is measured by undertaking a detailed topographic survey of the road surface and the adjacent verges. Traditionally, this is carried out by land surveyors using, for example, a theodolite, EDM and level.
