Raster Imagery in Geographic Information Systems is a practical guide to how raster data are collected, processed, incorporated, and used in vector GIS applications. The book provides a general discussion of how raster data are collected by remote sensing instruments, how they are used to form images, and how they complement vector data. In addition, the book contains over 50 case studies across the application spectrum in how private and public sector organizations are currently using raster data. Covers how the spectral contents of raster data can be used in cultural and natural resource applications; how raster data are rectified into orthophoto products and how global positioning systems (GPS) technology improves their use to accurately locate pixels on the ground; how raster data are processed for a variety of generic heads-up applications; case studies in forest management; case studies in hydrology, agriculture, and meteorology; case studies in landscape analysis, land use/land cover, and urban and regional planning; case studies in environment and mineral exploration; and case studies in economic applications and diverse modeling scenarios.
