12Orthophotomap Creation with Extremely High Buildings
12.1Introduction
For urban areas with very high buildings, the traditional method is not capable of orthorectifying the relief displacements caused by high buildings. Therefore, a so-called true orthoimage map (TOM) generation method was presented by a few researchers, such as Amhar et al. (1998), Rau et al. (2002), Nielsen (2004), Biason et al. (2004), Mayr (2002), Palà and Arbiol (2002), Siachalou (2004), Habib et al. (2006), Zhou et al. (2005), Sheng et al. (2003) and Xie and Zhou (2006). Briefly, the TOM generation is composed of digital terrain model (DTM)-based orthoimage map generation, digital building model (DBM)-based orthoimage map generation, and their merging. The associated ...
