Cadastre

The word cadastre came into English through French from the Greek (), a list or register, from ()—literally, "(organised) line by line". A cadastre commonly includes details of the ownership, the tenure, the precise location, the dimensions (and area), the cultivations if rural, and the value of individual parcels of land. Cadastres are used by many nations around the world, some in conjunction with other records, such as a title register. The International Federation of Surveyors defines cadastre as follows: A Cadastre is normally a parcel-based, and up-to-date land information system containing a record of interests in land (e.g. rights, restrictions and responsibilities). It usually includes a geometric description of land parcels linked to other records describing the nature of the interests, the ownership or control of those interests, and often the value of the parcel and its improvements. ==History==

mountains, 2018 Some of the earliest cadastres were ordered by Roman Emperors to recover state owned lands that had been appropriated by private individuals, and thereby recover income from such holdings. One such cadastre was done in AD 77 in Campania, a surviving stone marker of the survey reads "The Emperor Vespasian, in the eighth year of his tribunician power, so as to restore the state lands which the Emperor Augustus had given to the soldiers of Legion II Gallica, but which for some years had been occupied by private individuals, ordered a survey map to be set up with a record on each 'century' of the annual rental". In this way Vespasian was able to reimpose taxation formerly uncollected on these lands. With the fall of Rome, the use of cadastral maps effectively discontinued. Medieval practice used written descriptions of the extent of land rather than using more precise surveys. Only in the sixteenth and early seventeenth centuries did the use of cadastral maps resume, beginning in the Netherlands. With the emergence of capitalism in Renaissance Europe, the need for cadastral maps reemerged as a tool to determine and express control of land as a means of production. This took place first privately in land disputes and later spread to governmental practice as a means of more precise tax assessment. ==Surveys==

A cadastral map is a map that shows the boundaries and ownership of land parcels. Some cadastral maps show additional details, such as survey district names, unique identifying numbers for parcels, certificate of title numbers, positions of existing structures, section or lot numbers and their respective areas, adjoining and adjacent street names, selected boundary dimensions and references to prior maps. James C. Scott, in Seeing Like a State, argues that all maps, but particularly cadastral maps, are designed to make local situations legible to an outsider, and in doing so, enable states to collect data on their subjects. He sees the origins of this in Early Modern Europe, where taxation became more complex. Cadastral maps, he argues, are always a great simplification, but they in themselves help change reality. ==Documentation==

Cadastral documentation comprises the documentary materials submitted to cadastre or land administration offices for renewal of cadastral recordings. Cadastral documentation is kept in paper and/or electronic form. Jurisdiction statutes and further provisions specify the content and form of the documentation, as well as the person(s) authorized to prepare and sign the documentation, including concerned parties (owner, etc.), licensed surveyors and legal advisors. The office concerned reviews the submitted information; if the documentation does not comply with stated provisions, the office may set a deadline for the applicant to submit complete documentation. The concept of cadastral documentation emerged late in the English language, as the institution of cadastre developed outside English-speaking countries. In a Danish textbook, one out of fifteen chapters regards the form and content of documents concerning subdivision and other land matters. Early textbooks of international scope focused on recordings in terms of land registration and technical aspects of cadastral survey, yet note that 'cadastral surveying has been carried out within a tight framework of legislation'. Cadastral documentation is described, e.g. for Finland as follows '8. Surveyor draws up cadastral map and cadastral documents … 10. Surveyor sends cadastral documents to cadastral authority.' In Australia, similar activities are referred to as 'lodgement of plans of subdivision at land titles offices' ==Management==

Cadastre management has been used by the software industry since at least 2005. It mainly refers to the use of technology for management of cadastre and land information in geographic information systems, spatial data infrastructures and software architecture, rather than to general management issues of cadastral and other land information agencies. ==Cadastres in different jurisdictions==

United Kingdom In Scotland there is a Cadastral Map: Land Registration etc (Scotland) Act 2012. In 1836, Colonel Robert Dawson of the Royal Engineers proposed that a cadastre be implemented in light of his experiences on secondment to the Tithe Commission. In England, Wales and Northern Ireland there is a system of land registration with similar functions, but the word "cadastre" is not used. United States In the United States, cadastral survey within the Bureau of Land Management (BLM) maintains records of all public lands. Such surveys often require detailed investigation of the history of land use, legal accounts, and other documents. The Public Lands Survey System is a cadastral survey of the United States originating in legislation from 1785, after international recognition of the United States. The Dominion Land Survey is a similar cadastral survey conducted in Western Canada, begun in 1871 after the creation of the Dominion of Canada in 1867. Both cadastral surveys are made relative to principal meridian and baselines. These cadastral surveys divided the surveyed areas into townships. Some much earlier surveys in Ohio created 25 square mile townships when the design of the system was being explored. Later, the design became square land areas of approximately 36 square miles (six miles by six miles). These townships are divided into sections, each approximately one-mile square. Unlike in Europe, this cadastral survey largely preceded settlement and as a result greatly influenced settlement patterns. Properties are generally rectangular, boundary lines often run on cardinal bearings, and parcel dimensions are often in fractions or multiples of chains. Land descriptions in Western North America are principally based on these land surveys. ==Extensions==

Extensions of the conventional cadastre concept include the 3D cadastre, considering the vertical domain; and the multipurpose cadastre, considering non-parcel data. According to the UN Economic Commission for Europe, a "Marine Cadastre describes the location and spatial extent of rights, restrictions and responsibilities in the marine environment". Marine cadastres apply the same governance principles to the water. They help further conservation and sustainability efforts. A related concept is that of marine spatial data infrastructures. ==See also==
