3D Geometries in Spatial DBMS

Database management systems (DBMS) have significantly changed in the last several years. From a system dealing with management of administrative data they have involved to a spatial DBMS providing spatial data types, spatial indexing and extended spatial functionality. Mainstream DBMS support mostly a geometry model but the first natively supported topology model is already a fact. Although the provided functionality is limited to the second dimension, various options exist for management of three-dimensional data. This paper discusses some of them, present current research and outline directions for further extended management of 3D data. The paper is limited to the geometry model, i.e. topology issues are not covered. Evolving to Spatial DBMS DBMS have been traditionally used to handle large volumes of data and to ensure the logical consistency and integrity of data, which also have become major requirements in handling spatial data. For years, spatial data used to be organized in d...
