The new generation of aerial photogrammetric cameras brings camera constructions with several fields of view, instead of a traditional vertical one, which, in addition to vertical images, also enable oblique images. Although this imaging method allows higher quality when making a 3D model of the imaged area, it is still not used in Croatia. This paper describes the technology of aerial photogrammetric cameras with multiple fields of view and the advantages of using nadir & oblique aerial imagery, especially in photogrammetric algorithms that allow automated orientation and measurement of images. The tests were performed on nadir and oblique images taken by Vexcel Osprey nadir & oblique camera. Finally, the result obtained only with vertical images was compared with the result with oblique images when making a 3D model of the urban area. Special attention to the quality of modeling of buildings and urban vegetation is drawn and discussed.
