The objective of this workshop is to provide an overview of one approach to the modelling of spatial objects, including landscapes, within a GIS context. This course is primarily aimed at postgraduates in GIS/Cartography and Computer Science. The workshop is intended to provide a theoretical and practical framework for the development of 2D and 3D GIS applications. The emphasis will be on dynamic topological data structures, visualization and interaction. 

Lecture 1: Basics of Voronoi/Delaunay Algorithms, Graphs, geometry, 2D Graph data structures, models of space and the simple point Voronoi diagram:

Lecture 2: Advanced Voronoi/Delaunay Algorithms and Applications. The crust and skeleton, point deletion and Sibson interpolation, the kinetic point VD, and the 3D Voronoi diagram.

Lab 1: Demonstration software:

A variety of demonstration software products will be made available. These include: an interactive 2D DT/VD program; a line segment VD program; a Marine GIS demo; terrain modelling software, and a 3D VD package.

Lab 2: Terrain Modelling Project

In the afternoon there will be a class project. Students will have previously prepared a scan or sketch of a small simple contour map. The scanned image will be used to prepare a set of data points and a triangulated terrain model, and the resulting images will be submitted for review.
