| Summary: | Most major cities a rebeing managed spatially by 20 geo-DBMS, however, unlike Istanbul city it is in the verge of 3D spatial information system especially for the historical peninsular region. Thousands of its 3D objects (mainly buildings - old a nd new) are in the process of 3D da tabase development Istanbul city municipality is currently busy with various GIS projects including an initiative towards a 3D database for the city. This paper describes the development of 3D database from terrestrial laser scanned data where a leading geo -DAMS, i.e. Oracle Spatial 109 were utilised . Useful 3D geoinformation could be generated from such 3D database, thus the initiative would provide an excellent tool fo r the city's decision making process e.g. for the city planning purposes. and etc. The 3D geo-database approach described III this paper is certainly would be very beneficial 10 the city and other GIS users since the current and commercial GIS software face some difficulties in providing such GIS operations and information to the relevant authorities. The paper also highlight s new 3D spatial operations developed for possible spatial analysis of 3D objects (surface and underground objects). |
