The combination of vertical with oblique image cameras in only one mechanical set is not a new invention. As early as 1900 Scheimflug invented a camera with 8 oblique lenses and one nadirlens. Since then, different setups have appeared in the industry with some success in their application. Lately, the advent of new POS technology as well as the new digital CCD chips being used in the commerciallyavailable mid-size digital cameras has revived this sort of image data acquisition that allows the 3D-reconstruction of the object space from aerial images. Satellite imagery is also used with the same purpose. Applications are countless, nearly all being related to 3D-modeling of engineering objects and the 3D mapping is that objects can be classified and joined in layers that, along with the incorporation of their attributes, will form the basis of a multitude of 3D GIS applications. The present paper is a summary review of the latest acquisition systems, their advantages and disadvantages, complex geo-spatial tasks to be followed for a better review of cases studies and projects that are presented and analyzed from both visual and statistical viewpoints.
