Döner, F.
In Turkey, cadastral surveys have been carried out by various measurement techniques, at different standards and based on different legislation. Consequently, one of the most important problems with the cadastre is that approximately half of the current cadastral maps are insufficient to meet the expectations of today’s modern cadastre. In order to resolve the problem and renew the cadastral maps, the General Directorate of Land Registry and Cadastre commenced the Land Registry and Cadastre Modernization Project in 2009. Within the scope of the project, it is intended that 10 million parcels will be renewed by the end of 2014. This study aims to evaluate the cadastre renovation studies in Turkey with respect to their legal and technical aspects using a case study area. Results show that cadastre renovation studies may be insufficient to enrich and update the cadastral data. As a solution, legal amendments should be made in the Cadastre Law in a manner that will allow a new cadastral survey to be performed.

Döner, F.; Biyik, C.
In this paper, an overview of phases for modelling and mapping third dimension of spatial objects in a database is presented based on a selected spatial database management system (DBMS). These phases include (1) defining a spatial reference system for representing three-dimensional (3D) objects with real-world coordinates, (2) geometric modelling of 3D objects in the database, (3) 3D spatial indexing for fast accessing/querying the 3D data, 3D spatial queries and representation of 3D data. Then, a case study is performed to assess needs, possibilities and potential limitations of 3D data modelling in the spatial database.
