Abstract

One of the 3D GIS research areas is the data management of 3D objects. Geo-database is part and parcel of the GIS technology which provides ways to store and manage large spatial data sets. Recently there is a growing demand in 3D spatial information among the community. Present GIS is mature enough to handle 2D situation but lack to cater 3D data. Thus, the needs for managing the 3D spatial datasets are really necessary. Besides this, data acquisition technique has also motivates us for a more practical data structure(s) towards a data model for 3D GIS. A discussion on how to establish these data structures for managing 3D spatial objects form major discussion of this paper. 3D primitives like points, lines, polygons and solids are part of the primitives. The mapping of this structure in Oracle Spatial will be highlighted as well. Since geo-spatial database can handle large amount of data, we propose a practical data management and test by using real world datasets. In the experiment, the management of the 3D objects and appropriate indexing method is also discussed.
