What are the turning points in ISPRS history?
This question could be answered in several different ways: in terms of the management of ISPRS or the development of technologies in photogrammetry, remote sensing and spatial information sciences. A good paper on this topic was given by Professor Murai at the ISPRS Commission II Symposium in Xian in China. A copy will be available on ISPRS Web site shortly. It would be worth consulting that paper for more details. As far as the administration of ISPRS is concerned, a major turning point occurred in 1948 when the details of six Technical Commissions were defined, while the seventh was added in 1952. These are the seven Technical Commissions that exist today. A further major turning point was the change of name to include remote sensing in 1980. Although this change did not impact on the work it was undertaking, it recognised the areas that were being studied by ISPRS. In terms of the technology developments, the turning points are defined in terms of technology three eras of developmen
