The underground cadastre and its implementations in Turkey
Karatas, Kamil, Cemal Biyik and Osman Demir
Planning the infrastructures facilities which have urban life and development level parameters and their applications on the ground are the most important duties of the city managers. These infrastructure facilities are water, sewerage, natural gas, electricity, telecommunication, metro and tunnel. There is spatial data need for these infrastructures which satisfies desired precision criteria as it is demanded all of the engineering constructions. First of all, the relationship with the properties should be identified very clearly for determining the optimum infrastructure routes. Thus, there is a need for an information system which has related to the properties questions such as; what, where, how much, who is the owner, what its geological situation, what kind of plant cover and engineering buildings has on it? When looking from this perspective there are some issues with these infrastructure facilities on the phases of planning and application in Turkey. Due to these problems, there are property cases encountered mostly on where the infrastructure facilities had been established. The basic problem is lying on the data infrastructure which does not satisfy the demanded standards for the needs of an optimal planning. In order to overcome these problems the purposee part of cadastre law was changed in the year 2005. By this change, the subject that the data base of spatial information systems are to carry out by cadastre works was added to the cadastre law. In this point of view, an information system model can be designed by adding infrastructure facilities data into the scope of spatial information. However, in the scope of parcel based information systems, the content and the scope of infrastructure facilities should be defined. The data acquired by infrastructure cadastre should be identified with the standards. In this paper, the questions of what are the infrastructure facilities, how the relationships between land properties and the infrastructure facilities are examined in order to fit underground cadastral concept into the current Turkish Cadastral system.
