57 that this gathering of data represents probably about 90% of the effort and cost of a land information system. This shows the result of letting computer experts and geographers get the upper hand in this field. Unfortunately they do not understand the basic requirements of surveying and mapping. They are assuming that the "data" is somehow available. They are also not aware of the fundamental principle ruling surveying and mapping operations which states that "smaller scale" products can be derived from the " larcrer scale“ data but not vice versa. Therefore, since one can not avoid relatively precise and detailed measuring operations in the field or by using photogrammetry, the proper and only economic solution in the age of computers is to carry out tnese measurements correctly, and then derive smaller seale and generalized products from them by the use of computers. Ev doing so, the precise up-to-date terrain data would be available whenever required. Delays, duplications and blunders would be eliminated and the savings 'would be enormous. Moreover, a needed base would be created for the acquisition and efficient use of other data such a.s that provided by remote sensing techniques. To keep the various surveying and mapping techniques in a natural operational structure, it is not sufficient to rename societies and their journals. One must formulate new operational principles and rational specifications including alternative measures that permit the use of photogrammetry. After all, it is the only technique capable of solving without delay the pressing problems in the field under discussion. The guiding factors must be the actual requirements of society at larcre and not the vanity or commercial interests of various groups. Photogrammetry, because of its wide range of applications and singular efficiency, forms an obvious base for such a comprehensive and integrated land information system. Such a system is urgently needed in all countries, but in particular in developing countries. They do not have the time or resources to enjoy the "luxury" of obsolete schemes. In order to achieve this goal some organized effort on our side is required. First of all, we should ask ourselves the basic question: Are we satisfied with the present state of surveying and mapping in the world, and do we really think we have carried out cur responsibility in this field? If the answer in "No", we should then ask ourselves, "How did this happen?". We know mat pcwerrul and economic facilities are provided by photogrammetry; why the lack of progress? Secondly, if we. are concerned enough not to be satisfied with the present situation, we should remind national and international institutions that as far back as 1972 the UN Secretary General appointed an Ad Hoc Group of Experts * that subsequently issued a report entitled ,, Medium-Scaie”and Large- Sca 1 pubi the expl f ina dire embe done ther chec comm the alar prog prob resp Comm this ACKN REFE Blac B1 ac Vili Gare B1 ac
