Determination of the parcels committing coastal contravention via the geographical information systems: Sample of Samsun

Abstract

It is clearly stated in the Constitution and Civil Law, being in the first place, and in Municipal Law, Cadastral Law and Coastal Law that the coasts are under the provision and austerity of the government and that public interest shall be pursued for benefiting from these areas. In the 715 article of the Law, 16/c article of the Cadastral Law and 79 article of the Municipal Law, it is specified that private ownership can not be in question on the coasts and those areas can not be suspended. Additionally, in accordance with the 5th article of the Coast law, numbered 3621/3830, the determination of the shore border line is compulsory in order to perform planning and application on the coastal and shore line. Since the available real estates on the coastal areas are very significant, where public interest shall be given particular importance, determination and plannings of the shore border line shall be made very carefully. However, due to precipitation and since the determination of the shore border line is not performed as it should be and in time, utilizations outside of public interest are seen. The first and the most important step of our country concerning protecting the coasts of seas, lakes and rivers and shores which are follow-up of these is the determination of the shore border line. In this study, different areas were determined in the district of Atakum and its towns on the western shores of the province of Samsun and the relationships of the shore border line-landownership were examined in the given areas. In order to make researches and examinations in these areas, primarily; cadastre sheets were supplied from the Cadastral Directorate, landownership information related to the real estates were supplied from the Real Estate Registration Offices and determinations of the shore border line were supplied from the Provincial Directorates of Public Works. Digitizing the acquired data, softwares of the geographical information systems and data which were kept on different layers could be superposed, shore border line was processed onto the status of landownership and the relationships of the shore border line-landownership were examined through making the required spatial analysis and inquisitions. In the examinations, the extents of the shore border line contravension were calculated for the parcels in which the shore border line passes through the landownership border. The examinations here were performed by taking the determination dates of cadastre and shore border line into consideration, as well. Additionally, geological characteristics in the study area were determined appropriately for the parcels which would not be subject to the private land ownership since they are within the shore border line and which were required for the Title Cancellation. As a result of the sieve analysis performed in the research area, geological structure was determined to be sand and sand full of shells. Key words: Coast, shore border line, landownership, cadastre, geographical information systems, coastal contravention.
