In this paper the ESPRIT-III GLORE project is described. One aim of the prject is to create a turnkey system that takes as input hundreds or thousnads of aerial video images and outputs a digital ortho-mosaic and a digital elevation model of the covered area. This '3D-image- mosaic' is to be used by the forest industry in land-use planning and forest management. The mosaic is to be used as basis for the evaluation of forest resources. It is very difficult to use the separate video images, so the mosaic is essential. The digital elevation model is important in planning of roads and visualization. The '3D-image-mosiac' is to be made automatically using the methods of global object matching or global object reconstruction. In this case an object based approach is used in the matching. This kind of methods are mostly very computation intensive. Therefore a transputer based parallel computer is used. First, the ideas behind the system are described, including the use of GPS navigation data with the on-line digitization of the images on the aircraft. Then, some examples of the method using aerial photographs are shown.
