Abstract
Abstract. Projects based on Geographic Information Systems (GIS) have started within the body of the General Directorate of Land Registry and Cadastre (GDLRC) by the Land Registry and Cadastre Information System (LRCIS) in the beginning of 2000s. LRCIS was followed by other projects which are Turkish National Geographic Information System (TNGIS), Continuously Operating GPS Reference Stations (CORS-TR), Geo Metadata Portal (GMP), Orthophoto Web Services, Completion of Initial Cadastre, Cadastre Renovation Project (CRP), 2B and Land Registry Achieve Information System (LRAIS). When examining the projects generated by GDLRC, it is realized that they include basic functions of land administration required for sustainable development. Sustainable development is obtained through effective land administration as is known. Nowadays, land use becomes more intense as a result of rapid population increase. The importance of land ownership has increased accordingly. At this point, the necessity of cadastre appears. In Turkey, cadastral registration is carried out by the detection of parcels. In other words, it is obtained through the division of land surface into 2D boundaries and mapping of them. However, existing land administration systems have begun to lose their efficiency while coping with rights, restrictions and responsibilities (RRRs) belonging to land which become more complicated day by day. Overlapping and interlocking constructions appear particularly in urban areas with dense housing and consequently, the problem of how to project these structures onto the surface in 2D cadastral systems has arisen. Herein, the necessity of 3D cadastre concept and 3D property data is confronted. In recent years, oblique photogrammetry, whose applications are gradually spreading, is used as an effective method for producing 3D data. In this study, applications of oblique photogrammetry and usability of oblique images as base for 3D Cadastre and Land Administration projects are examined.
Highlights
1.1 Land AdministrationLand is a spatial magnitude, where all living creatures shelter, hold on to life and carry on vital activities throughout the history
Decisions can be taken either individually or by a group of people. Countries provide their existing lands to be managed with respect to requests, requirements and laws depending to the technological advancements
Oblique photogrammetry is a photogrammetric method, which combines conventional nadir images together with oblique images acquired at high angles to build 3D city models with texture data obtained from oblique images (Petrie, 2008)
Summary
Land is a spatial magnitude, where all living creatures shelter, hold on to life and carry on vital activities throughout the history. The modern land administration depends on the land management paradigm (Williamson et al, 2010) In this approach, land administration functions including land tenure, land use, land value and land development are treated as inseparable parts. Sustainable development consists of economic, social and environmental components and the basis of the paradigm is the Institutional Arrangements depending on the country context. This basis can be defined by the three legs, which are Land Policies, Land Information Infrastructures and Land Administration Functions for sake of sustainable development. The land management paradigm is required by modern land administration theory to make systems overcoming the land related right, restriction and responsibility issues for providing sustainable development (Williamson et al, 2010)
