Approximately 57.4 million cadastral parcels have been produced in Turkey
since its establishment. In this period, it was used different methods in the
produced of these parcels. Therefore, the cadastral data are not all of the same
standard in quality. According to the data of the General Directorate of Land
Registry and Cadastre (GDLRC), there are approximately 34 million parcels which
have been harmonized with the ground. The remaining parcels have temporary
coordinates in terms of data quality. Also, only 27 million of these parcels
are in the ıtf 96 datum. Turkey has been carrying out important work towards
modernizing the technical cadastral infrastructure for a long time. GDLRC has
declareted that it will updated 22
million parcels in the near future. Acording to Cadastre Law, there are three
different methods in updating of cadastral maps in Turkey. These are basic
technical error correction, digitization and updating methods. The aim of these
methods is to improve the quality of cadastral maps, to provide its harmony with ground and to
convert them to a common reference system (ITRF: International Terresterial
Reference Frame). Technical error correction is applied in one or more parcels.
The digitization method is mostly carried
out on the cadastral block or village/neighborhood scale in urban areas. The
updating method is preferred when the input of a local expert-witness is needed
in rural areas. After legislative regulations, the content and scope of the
updating method, which is called initially cadastral renovation has been
expanded and transformed into an updating method. In this study, it will focus
on the current status of Turkish cadastre data quality and the cadastral
updating methods applied there.
In addition, the role of the private sector in
the implementation of these methods will be discussed.
