Açık Kaynaklı CBS Topluluğu (Open GIS Consortium-OGC), Dünya Sanal Doku İşbirliği Topluluğu’nun (World Wide Consortium-W3C) ürettiği Genişletilebilir İşaretleme Dili (Extensible Markup Language-XML) teknolojisine dayalı olarak 29.01.2003 tarihinde Coğrafi İşaretleme Dili (Geography Markup Language-GML) “GML 3.0” sürümünü çıkarmıştır. 15 Temmuz 2005 tarihinde yürürlüğe giren Büyük Ölçekli Harita ve Harita Bilgileri Üretim Yönetmeliğinde Ulusal Veri Değişim Formatı (UVDF) tanımlanmış ve üretilen haritaların, bu formata göre oluşturulacak XML şemasına uygun arşivlenmesi düzenlenmiştir. Tapu ve kadastro verilerinin, OGC standartlarını benimseyen INSPIRE (Infrastructure for Spatial Information in Europe) çalışmalarında bir katman olarak oluşturulması planlanmıştır. Ayrıca, tescile esas güncel ve güncel olmayan tapu ve sayısal kadastro verilerine kolay ulaşabilmesi kullanımda gerekli olmaktadır. Bu nedenlerle tapu ve kadastro verilerinin GML şemalarına dayalı XML ile imlenme ihtiyacı oluşmuştur. Yapılan çalışmada öncelikle, tapu ve kadastro verilerinin imlemesine ait Bütünleşik Modelleme Dili (Unified Modelling Language-UML) sınıf diyagramı oluşturulmuş ve GML kök şemalarını kullanan GML uygulama şeması hazırlanmıştır. GML uygulama şemasına göre XML imlemelerinin yapılışı örnek üzerinde gösterildikten sonra kullanımda olan bir sayısal kadastro paftası ve ilgili tapu verisi imlenmiştir. Sonuçta, hem sayısal kadastro paftaları ile tapu bilgilerine ait güncel ve güncelliğini yitirmiş tescile esas verilerin GML şemalarına uygun imlenmesine hem de UVDF’ye uygun üretilen haritaların sayısal kadastro haritalarıyla ilişkilendirilebilmesi için bir yöntem önerilmiştir.

Geography Markup Language-GML was developed by Open GIS Consortium-OGC. OGC presented GML Version 3.0 on January 29, 2003 based upon the technology of Extensible Markup Language- XML developed by World Wide Web Consortium- W3C. National Data Exchange Format (NDEF) was defined in the Regulation for Production of Large Scale Maps and Mapping Information that came into effect on July 15, 2005, and the maps produced were designed to be archived in line with XML schemas to be formed according to this format. It was planned to constitute a layer for land registry and cadastral data at studies of INSPIRE (Infrastructure for Spatial Information in Europe) that adopted OGC standards. It is of great importance to digitize all current and outdated land registry and cadastral data which are subject to registry, in order for the requesting organizations to make accurate and rapid timely analysis and to access to these data easily. Considering the conduction of time-analysis and digitization of data subject to registry, it became compulsory to mark the land registry and cadastral registry data with XML based on GML schemas. Having the title-deeds and registry data delivered to users through web with this marking, not only the maps produced according to NDEF can be related to digital cadastral maps but also “Land Registry and Cadastre Information Layer” will be formed which is included in action plans within the Project etransformation Turkey carried out in parallel to Lisbon Strategies Studies updated as i2010 in 2005. There are problems of the use of maps in Turkey together with other maps produced from different producer because they are not digital and do not conform to a common standard. It is necessary for many applications that land registry and cadastral data exist on the maps. Land registry and cadastral data on hand do not conform to a common standard format on digital environment. To prevent economic disadvantage on map production, NDEF was developed and was put in order in the instructions (the Regulation for Production of Large Scale Maps and Mapping Information). Moreover, NDEF was converted to the open source and interoperability technology Extensible Markup Language (XML) in this instructions. In this study, for the time analysis to be made, digital land registry and cadastral sheets were marked according to an application schema prepared using GML schemas developed with XML technology that is among the information technology tools supporting the open source and interoperability. In the application section of the study, two exemplary neighbouring sheets and land registry information that can enlighten all possible applications were prepared in the beginning. According to the sample cadastral sheets (spatial data) and registry data (non-spatial data), Unified Modelling Language-UML class diagrams of the land registry and cadastral data were formed and GML application schema that utilized GML basic schemas was prepared. Sample sheets were marked according to the prepared GML application schemas and queries that could be made according to these markings were shown. Then marking of a digital cadastral sheet in use and related land registry information was conducted, and how the application prepared for the thesis would be used was shown. Additionally, utilizing XML, Extensible Stylesheet Language Transformations-XSLT, XML Schema Definition Language-XSD, Scaleable Vector Graphic-SVG and Hypertext Markup Language- HTML technologies of W3C, presentation of land registry and cadastral data was exemplified on a Web site which was prepared as to be improved according to the developments in these technologies. It is coded by using XSLT, for geometric data in SVG and for non-geometric data in HTML. All documents are linked on a WEB page. To determine the coordinate information of the cadastral parcels was prepared an XML document. This document uses GML schemas and links to European Petroleum Survey Group parameter (EPSG). To determine the coordinate information of SVG documents was prepared Resource Definition Framework (RDF) code. A program was developed for the users using Visual Basic. Net. This program enables preparation of new document, recording the prepared document in the data base and retrieving it and querying the data from the data base. The users can make by means of this program validating and well form control of the documents. Finally, a method was developed to store and transport present land registry and the digital cadastral maps on the Web being used open source and interoperability technologies.
