摘要：In the generation of photogrammetric products with large terrain coverage (Orthophoto, DTMs) some crucial issues like the application of DG / ISO procedures, the management of high amounts of data or the efficiency of automatic measurement (matching) arise. Nevertheless, in spite of the acknowledged progress in this matter, there are still some other relevant tasks - like the map plotting - that still require a great deal of work and that still are far away from a complete automatic flow. In order to analyze the stereoscopic accuracy (both horizontal and vertical), a measuring test has been performed with different image scales (GSD of 7.5 – 10 cm, 45 – 50 cm). These measures have been realized with digital workstations (Digi3D) and analytical plotters (LeicaSD2000). We have worked with a large number of stereoplotter operators from both public and private companies. We have analyzed the planimetric accuracy which depends on the image scale and also the height accuracy which depends on the image scale and also on the base / height ratio
