摘要：In Aerial Photogrammetry some tools are available to simplify the aerial mapping planning and make it faster. In particular, once defined the scale of the map, witch is related to the Spatial Resolution (SR), diagrams are available to provide the average scale of photogram and the flying height for different focal length values. Terrestrial Photogrammetry is deficient in this kind of tools, probably because of the greater complexity and the lack of standardization in the parameters of the camera, and because of the presence of constraints on the camera distance and on the angle of view. The basic idea of this work is to obtain some tools to help mapping planning in terrestrial photogrammetry. We establish as project parameters the equivalent focal lenght, the camera distance and the camera resolution, all these variables are function of an assigned SR. We produced two typologies of graphs to help mapping planning: we have assigned or the camera resolution or the equivalent focal length in order to obtain some graphs where the other two parameters are plotted as function of the SR
