173 Nevertheless, it would not be surprising if the mechanically opera ting parts of this equipment are worn out within a few months and have to be replaced. This could even be considered a small price to pay for the increased speed of data processing. The previously mentioned fear of automation in general and of computers in particular, is in my opinion, steadily decreasing. Apart from the fact that people are becoming familiar with the idea of automation, many will appreciate the advantages of automation over the disadvantages that certainly exist. The attainment of the standard of living, as seen, for example, in large parts of the U.S.A. and in a number of Western European countries is ultimately attributable to their advanced technical development, of which automation is a part. If 3,000 million inhabitants of the earth are to be fed, clothed, and sheltered to decent human standards, and are to be given the opportunity and means to relax, we indeed need automation very sorely. Section 2automation of measurements of angle and distance The most important advantage to be gained from the automatic recording of field observations is not the saving of time but rather the elimination of errors in booking. The present form of recording measurements according to the grid marking system, even with the use of so called mark-sensing cards, or data copies translated by optical card copy readers (IBM 1231, IBM 1232, IBM 1287) into "punched" form, or other variants, cannot be considered as automatic registration. The form of recording mentioned here is useful only if one intends to mecha nize the processing of field measurements as far as possible. In Holland a system like this is used at the Koninklijke Neder- landsche Heidemaatschappij. See [19], [20] and [21]. A similar system developed in Western Germany, is described in [22]. The grid marking system as such can undoubtedly be made usa ble for the direct recording of instrument readings provided the relative parts of, for instance, the punched card, are marked by pressing a button. The trouble, however, is that on account of its bulk and weight conventional punch card equipment is not suitable for such a development. In the near future micro-circuits and micro-punching equipment will play a role in this. The system of direct recording of observations mentioned in my last report, as developed on the instructions of E. Lang by the firms of Fennel and Kern in cooperation with Zuse, is the most used system at the present moment. However, its application only extends over a limited field (see section 1). The application for patent, which was made in i960, summarizes the system as follows: for the recording and direct processing of field results by electronic computers, the theodolite is provided with coded numerals beside the familiar circles and numerals. If the theodolite is equipped with an optical micrometer its circle is also coded. Auxiliary readings,
