Welcome to the Line Generalisation Algorithms Teaching and Learning Tool. This interactive learning module consists of various lessons aimed at developing an understanding of the operation of vector line generalisation algorithms. On completion of the Line Generalisation Algorithms learning module, students should have a strong grasp of concepts involved in simplifying and smoothing lines, as part of vector-based GIS.

There are five components to the Line Generalisation Algorithms interactive learning module: Specific Theory, Lang Simplification Algorithm Visualisation, Lang Simple Interactive Example, McMaster's Slide Averaging Algorithm Visualisation and Questions with Feedback. In general, each component assumes knowedge gained from the previous component(s), particularly the Specific Theory. Thus for best results, it is suggested that students work through all components of the Line Generalisation Algorithms interactive learning module in sequential order, with the testing component attempted last. Downloading and printing the material presented in the Specific Theory component is recommended for later reference.
