"This book fills a void of telling and showing the reader how remote sensing as a part of geomatics really works. Dequal, Professor of Topography and Photogrammetry, DITAG, Polytechnic of Turin, Italy The objective pursued is to publish an integrated text, containing simple and comprehensible concepts relevant to experts in Geo-spatial Information." "The book is rigorous and synthetic, describing with precision the main instruments and methods connected to the multiple techniques today available. At the same time, the book is rigorous and synthetic, describing with precision the main instruments and methods connected to the multiple techniques available today. Gomarasca, one that is only apparently modest, is to publish an integrated text on the surveying theme, containing simple and comprehensible concepts relevant to experts in Geo-spatial Information and/or speci cally in one of the disciplines that compose it. These specialized elds are intimately interrelated in terms of both the basic science and the results pursued: rigid separation does not allow us to discover several common aspects and the fundamental importance assumed in a search for solutions in the complex survey context. Geo-spatial Information embeds topography in its more modern forms (measurements with electronic instrumentation, sophisticated techniques of data analysis and network compensation, global satellite positioning techniques, laser scanning, etc.), analytical and digital photogrammetry, satellite and airborne remote sensing, numerical cartography, geographical information systems, decision support systems, WebGIS, etc. A more meaningful and appropriate expression is G- spatial Information or GeoInformation. It includes several disciplines and te- niques for the study of the Earth’s surface and its environments, and computer science plays a decisive role. Geomatics is a neologism, the use of which is becoming increasingly widespread, even if it is not still universally accepted.
