49 By cadastral surveying I mean the mathematical definition of parcels of land in a uniform, country-wide system that uses a coordinate system and large-scale multipurpose maps together with permanent registers containing number of pertinent informations, among them alphabetic register of land owners and numerical register of parcels. By legal surveying I mean the measuring of parcels of land to provide their size, shape and the relative location. This information is usually in a form of a diagram of property boundries frequently accompanied by their verbal description. Often such diagrams show no connection to adjacent surveys. Skipping entirely a discussion of the relative merits of these quite different systems, one must notice that despite the impressive advancement in the technology of surveying and mapping both types operate using concepts formulated centuries ago. When accepting new techniques, (often with hesitation and resistance) such as, for instance, the use of computers for the processing, storage and display of data, no effort is made to formulate new operational concepts. The result is that the cadastral or legal survey specifications do not allow and advise the use of powerful, simple, fast and economical photogrammetric techniques. Certainly, appropriate adaptions could permit the entry of photogrammetry as an essential part of a dynamic multipurpose cadastre, constituting a general land information system. From such a system a multitude of other surveying and mapping products could be derived. Without such a system no meaningful progress can be made in one provision of land information systems that are desperately needed everywhere but particularly in many developing countries. At present, if anything, the situation is getting worse in view of the rapidly growing world population and the new demands resulting from socio-economic changes. The loser is society at large, again particularly in developing countries. But there are other losers. These are the members of our profession (photogrammetrists and surveyors alike) who through their own indolence and, yes, ignorance, are being forced from some areas of their traditional responsibility. In order to assess properly this embarrassing state of affairs, one must first take a detached and rather global view of scientific and technical advances in general, then look at our apparent incapability of solving technically trivial but economically important problems. Indeed we must remind ourselves that we are living in the era of the conquest of the moon, during which ama singly detailed maps of the celestial bodv were produced. I will pass over the often incredible possibilities provided by advancements in physics, chemistry, biosciences, medicine and engineering. I must, however, mention some of the eifects of these advancements on our own field. We have now a whole new array of instruments to record the surface of the earth wit (Pi tec oth' dis com dis pro pos wou acc rea res me so the app ”wh; ope Th ma te f r di ph im ab' on be th c di r un or 0 f c 1 e r c s i p
