1 Abstract: Currently, a variety of software is capable of handling a wide range of spatial problems, beginning with approaches for describing spatial objects to quite complex analysis and 3D visualisation. However, an increasing number of applications need more advanced tools for representing and analysing the 3D world. Among all types of systems dealing(More)
This paper describes the 3D GIS research efforts done by the GIS research groups as well as by major GIS software vendors world wide, works done by the authors of this paper formed major discussion of this paper including a discussion on why the 3D GIS software is difficult to be realised. At the moment there is no real 3D GIS software available in the GIS(More)
We present some algorithms which construct a triangular graph given a set of points, where each face of the graph complies with the Delaunay criteria. Then we develop an linear time algorithm to construct the contour of such a triangular graph, where each face is coloured either black or white. Our techniques avoid expensive trigonometric computations. We(More)
The interest in 3D GIS increases due to developments in technology and necessity of users to cope with more complex tasks. Questions related to data acquisition, data storage, data analysis and data visualization are topics for investigations. A key issue on the way of building a 3D model, is an adequate data structure capable to respond to various user(More)
