The design of a temporal geographic information system for deed and cadastre data

SUMMARY The Design of a Temporal Geographical Information System for Deed and Cadastre Data 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). Deed and cadastre (DC) data is dynamic. These data have been updated conventionally. In our country, the temporal analysis of 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 spite of this need, in Turkey, determination of the need for temporary DC data or any system design devoted to this need have not been realized yet. In this study, determination of the need for temporal analysis of DC data and a system design devoted to this need were realized. 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 the context of determined needs, a database design concerning deed data was realized. As for, cadastral data, a temporal geographical information system data model suggested by the literature was chosen. Afterwards, deed and cadastre data were linked. This linkage process was realized via some interfaces designed and implemented within this study. DC processes (e.g. sale, subdivision, mortgage and type changes change) causing changes in DC data, temporal analysis of DC data, some non- temporal or timely analysis and interactive temporal quarries were also realized using these interfaces. With the designed system, temporal DC data can be obtained quickly and precisely. In the context of e-Turkey, the designed system will provide the retrieval of DC data on the internet for the foundations and institutions in need of this data. In addition to this, TKGM will serve temporal DC data and gain some economical benefits with an authorization arrangement for some foundations and with a suitable charging policy.
