Activities of the Cadastre in the Netherlands I Towards a multi-purpose Cadastre*) by ir. J. Polman, head of the department of automation of the Cadastral Service in the Netherlands. The actual activities of the Cadastre in the Netherlands are based on a long tradition. The Dutch Cadastre as an institute has been in existance for 150 years, and it is thus one of the oldest cadastral services in the world. The Cadastre may be old but it is not old-fashioned. On the contrary, in this period of 150 years its tasks and activities have exhibited a steady evolution. It is my privilege to tell you something about this. The original purpose of the Cadastre was the admini stration of landed property for a fair levy of land taxes. This tax was based on the area of the parcels of land and the profit made on it. From the very start the cadastral map has been used as a means to identify parcels involved in the transfer of real rights on real estate. Soon after the introduction of the cadastre the designation of parcels became obligatory in official deeds. For this reason the Cadastral Service turned moreand more to the task of affording protection to real estate. Part of this task was the surveying of boundaries in order to reconstruct such boundaries in case of discord. In this way the function of the Cadastre became mainly the supply of information on real rights on real estate and on the actual state of landed property. It is laid down in several laws that specific land data shall be recorded in the cadastral registers. It is also provided in various regulations that use has to be made of data from the cadastral registers and maps. In this way the original cadastral administration has developed into an impor tant source of information for both the government and private persons. In contrast with many other countries all basic tasks in property administration are fulfilled by a single institu tion: the Cadastral Service in the Netherlands. These tasks are: - keeping the Public Registers, containing all the deeds concerning the transfer of property and the establish ment of mortgages; - keeping the cadastral records of real rights on real estate; - surveying the boundaries of cadastral parcels; - making cadastral maps, representing the cadastral parcels. Inleiding gehouden op 23 juni 1982 tijdens de door de NVG georganiseerde studiedag in het kader van de bijeenkomst van het Comité Permanent van de FIG te 's-Gravenhage. 210 cadastral registers (rights) public registers (deeds) cadastral maps (parcels) survey documents (boundaries) The cadastral system is based on the following legal principles: - the principle of booking: no legal effect without registration of deeds in the Public Registers; - the principle of consent: the cadastral owner has to consent to transfer of ownership; - the principle of publicity: the Public Registers and the cadastral administration are public; - the principle of speciality: the cadastral parcel number is unique and guarantees the identification of real estate. These four principles have resulted in the present situation which in practice means that the Cadastre is a very reliable source of information on the rights in respect of real estate. On the basis of the traditional task of the Cadastre - the registration of property - a number of new activities has been developed. At the end of the nineteenth century the government decided to establish a national co-ordinate system. To this end a triangulation network has been realized at three levels of densification. The measurement and computation of this network was completed in 1930. Since that year it has been the task of the Triangulation Service of the Cadastre to keep the network up-to-date and to supervise the quality of the network. The infor mation on the triangulation points is available to all NGT GEODESIA 82
