Designing three dimensional property right database for Turkey

Abstract

Current cadastral systems are two dimensional. Therefore, three dimensional (3D) property rights and restrictions cannot be registered and their legal status not fixed in these systems. The need for 3D information is increasing day by day in vertical grown up cities. The cadastre, which was used for proposing land tax at the first time, is defined as the geographical information systems (GIS) used for modelling between human and land relationships; thus, the cadastre turns into multi-layer cadastre at the present time. Consequently, 3D cadastre should be examined in GIS and integrated with querying 3D right and at least property units in geospatial database should be restricted for modelling property rights and physical objects. By the reason of missing 3D topology, current information systems do not make 3D geospatial analysis perfectly. This paper aims that some 3D queries can be made in the created database. Conceptual and logical system design was implemented with unified modelling language (UML) by using Microsoft Visio 2003 software and data types which supported ESRI ArcGIS. On the other hand, 3D models were formed by using MicroStation V8 and ArcScene 9.0 softwares.
