Surveying in the Netherlands 212 photogrammetrische Probleme; viele Auslander werden hier im Gebrauch photogrammetrischer Verfahren und Instrumente unterrichtet. Das Laboratorium fiir Geodasie der Technischen Hochschule in Delft ist das wissenschaftliche Zentrum, an dem die Vermessungsingenieure ihre Ausbildung erhalten. An der Landwirtschaftshochschuie in "wageningen findet sich ein Labora torium für Vermessungskunde, das der Ausbildung der kulturtechnischen Ingenieure, der Forstingenieure und der Landschaftsarchitekten dient. Until about 1930 the Cadastre was for practical purposes the only surveying institution in the Netherlands. The maps used were based on measurements obtained in the early nineteenth century in accordance with French in structions. The scale most widely used was 12500 and this map generally satisfied requirements of the society of that day. With modern developments in public life, the need for accurate maps for varied purposes however increased. In individual cases the Cadastre responded to these requirements by new surveys, resulting in maps at 11000. In doing so, the Cadastre also kept its legal object in view by giving the greatest possible attention to accurate recording of the boundaries of real rights. In large engineering projects however so many other data were often needed for technical plan ning that the need was felt for other surveying organizations, with technical aims of their own. Mention should be made of the Surveying service (Meet kundige dienst) of Rijkswaterstaat, which is the government agency for hydraulic and highway engineering, of the surveying departments of the provinces Noord-Brabant and Overijssel and of the municipalities Amster dam, Rotterdam, Utrecht, The Hague, Tilburg and Breda. Nederlandse Spoorwegen (Neth. Railways) also created a separate service, followed by Nederlandse Heidemaatschappij and Gront-Mij, and some private firms too saw an opening for useful work. Thus in the Netherlands at present there are quite a number of institutions in the field of surveying. By its monopoly on the administration of real property however, the Cadastre remains the central institution where in collaboration with other services and private organizations all measurements relating to boundaries of property are brought together. Such collaboration often results in new cadastral maps at 11000, and a requirement on the
