Terrain modelling has been a well recognised topic for many years in the geo-sciences and it has found wide application, especially since the introduction of GIS.;Digital Terrain Modelling: Principles and Methodology is the only up-to-date book covering this range of topics. It provides comprehensive coverage of the field, starting from terrain analysis (using terrain descriptors), data sampling strategy, data acquisition technology, data quality control, theory and methodology for surface modelling, algorithms for triangulation formations, interpolation methods, models for the prediction of DTM accuracy, management of DTM data, multi-scale representation, contouring and other extraction of other features, as well as various applications.;The book treats the topic at a medium level of technical detail and is suitable for use as an MSc-level GIS textbook or for GIS researchers and professionals.
