This book collates a series of invited peer reviewed papers presented at the conference on geoinformatics and LIDAR held at the National Centre for Geocomputation based in the National University of Ireland, Maynooth. Current constraints in field survey and DEM construction are reviewed together with technical and applied issues around the new technology. The utility of the data in process modeling is also covered. The book provides great value to researchers in the field of geomorphology, geostatistics, remote sensing, and GIS, and is extremely useful to students and practitioners concerned with terrain analysis.
