Zusatztext … provides unique means for understanding and comparing different cropland mapping strategies by utilizing different satellite sensors and ancillary data sets. The chapters are well written for entry level through advanced level remote sensing or agricultural specialists, and each chapter can be read sequentially or separately. … thoroughly documents the techniques and error assessment methods utilized to develop the world's first global irrigated map derived from remote sensing data. … the numerous international authors, color plates, and national cropland statistical tables makes the book an attractive and authoritative reference for mapping global croplands from remote sensing data. —Curt A. Reynolds, Crop Analyst, Foreign Agricultural Service, USDA, Washington, D.C., in Photogrammetric Engineering & Remote Sensing , June 2010 Informationen zum Autor Prasad Thenkabail, John G. Lyon, Hugh Turral, Chandrashekhar Biradar Klappentext As 80 percent of all freshwater is used for irrigation! monitoring this usage is critical to any global strategies regarding conservation. At present! considerable uncertainty exists about the spatial distribution of irrigated areas due to the absence of global mapping as well as problems with the accurate reporting of irrigation. Emphasizing practical mapping technologies based on remote sensing! this book provides actionable approaches for estimating water use from irrigated and rain-fed croplands on a national! continental! or global basis. Written by leading experts working at the forefront of this critical area! it offers case studies from a variety of continents highlighting the subtle requirements of each.
