Satellites, aircraft, and unmanned aerial systems (UAS) collect imagery that can be displayed and analyzed within a GIS to extract important information.
To familiarize GIS professionals and students with the advanced Earth-imaging technologies available today, Esri published Essential Earth Imaging for GIS, which provides a basic education in remote-sensing technology, promoting the effective use of sophisticated multispectral and 3D imagery.
Chapters introduce readers to remote-sensing methods and types of imagery as well as how to display and enhance multispectral images, process images in a GIS to improve quality, generate 3D data, and visually interpret images in a GIS to extract information from them.
Essential Earth Imaging for GIS was written by Lawrence Fox III, emeritus professor of forest remote sensing and GIS at Humboldt State University in California. The book is available at online retailers worldwide, at esri.com/esripress or by calling 1-800-447-9778.
