Opis

Terrain modeling has been a recognized topic for many years in the geo-sciences, and it has found wide application, especially since the introduction of GIS. Digital Terrain Modeling: Principles and Methodology is the only up-to-date reference to provide comprehensive coverage of the field. The author discusses terrain analysis (using terrain descriptors), data sampling strategy, data acquisition technology, data quality control, and the theory and methodology for surface modeling. Other topics include algorithms for triangulation formations, interpolation methods, models for the prediction of DTM accuracy, management of DTM data, multi-scale representation and contouring and extraction. The book also addresses the application of this technology and knowledge. The author presents the information at a medium level of technical detail, so the volume is suitable for use as an MSc-level GIS textbook, or for GIS researchers and professionals.
