An abstract model of three-dimensional spatial data types
act Model of Three-Dimensional Spatial Data Types Markus Schneider & Brian E Weinrich University of Florida Department of Computer & Information Science & Engineering Gainesville, FL 32611, USA {mschneid, brianew} Although spatial objects of our world have an intrinsic threedimensional (3D) nature, 3D data modeling and 3D data management have so far been neglected in spatial database systems and Geographical Information Systems, which map c data mainly to two-dimensional abstractions. But increasingly the third dimension becomes more and more relevant for application domains like pollution control, water supply, soil engineering, urban planning, and aviation. Large volumes of 3D data require a treatment in a database context for representing, querying, and manipulating them efficiently. This paper aims at investigating the complex ineatures of 3D data and presents an abstract, formal data model called SPAL3D (Spatial Algebra 3D). The data model comprises a set...
