178 touched by electronic computing. The number of examples that can be quoted is almost inexhaustible. It is striking that little or no attention at all is paid to the automatic recording of field readings and yet this is the beginning of automation if carried through in the right way. GeodesyBarometric measurement of altitude [61] (Russia) gravimetry [62] (Italy) and [63] (Hungary); triangulation [64] (France)calculation of geodetic lines [65] (Western Germany) and [66] (U.S.A.) One may read about photogrammetric applications in [67] to [75]. Basically these publications deal with solutions of block adjustment problems. As regards lower geodesy, I may refer to publications [76] (level ling), [77] (measurements in town), [78] to [80] (railway measure ments), [81] and [82]. Electronic calculation applied to road construction is dealt with in [83] to [87]. I formerly drew attention to the fact that utilization of the electronic computer can result in the development of other methods for solving certain problems. Examples of this are given in publi cations [88] to [93]. It appears from the above that the lead which electronic com puting already had over automatic recording of field readings has grown to an important extent during the period covered by this report. The surveyor who for some reason cannot bring himself to have his calculations performed by a real computer, and yet wants to profit from modern developments in some way, may possibly use a so-called electronic desk calculating machine. It should be emphasised that such a machine cannot be compared with a com puter. The control exercised by man when effecting a certain calculation is, if programming has been executed well, completely taken over by the computer for that calculation. An electronic desk calculating machine is usually capable of performing successive actions without human interference, but any real control of calcu lation in this is out of the question. The operator has to come into action every minute. As a "multiplier" this machine is too expensive. Anyone who wants to get more out of it will soon be disillusioned, because its limitations will then appear. For almost 20 firms, the manufacture of electronic desk calculating machines represents part of their livelihood. Those who are interested in this equipment, in spite of the above remarks, are referred to publications [94], [95] and [96]. Section 4automation of mapping Automatic mapping on the basis of coded records on a field sheet (see for instance [97]) has made only little progress during the period covered by this report. Here and there it has indeed been tried to undertake something in this directionhowever, the trouble is that the preparations required to arrive at automatic actions are, at
