Temporal analysis of deed and cadastre data by geographic information system

Geographic Information Systems, which expose enormous improvements parallel to computer technology developments, become an important part of nowadays human life. Geographical information systems today mainly present the static position of the real world Whereas, the data change in the course of time and the fact that these are not reflected into the information systems or the fact that these are reflected in different time intervals spoils the information consistency. For this reason, time integration into GIS has gained importance in recent years and as a result of this, temporal GIS (TGIS) emerged to be able to answer more complicated spatio-temporal inquiries of different disciplines. TGIS enables recording, analysing, processing and visualizing the both spatial and temporal changes. In our country, the temporal analysis of Deed and Cadastre (DC) data is needed by jurisdiction, many public foundations and institutions, municipalities, private sector and citizens. This need has long been tried to be met by conventional DC systems. In Turkey, land information representing the legal status of real properties such as land, building-plot and building has two main components; one is the geometrical component (Cadastre) and the other is the ownership information (Deed). DC data is dynamic. These data have been updated conventionally. In the context of need determination, foundations and institutions needing DC data were determined. Besides, the current structure of Register of Deeds and Cadastre offices were examined to determine the conventional DC system. In this study, determination of the need for temporal analysis of DC data and a system design devoted to this need were realized.
