This remote sensing toolkit, put together by the Centre for Spatial Environmental Research (CSER) in Queensland, Australia, is a very impressive guide for those new to remote sensing, or those simply looking for more information and clear definitions. The toolkit provides information on remote sensing as it is used in mapping. The toolkit features three separate sections – marine, terrestrial, and atmospheric – encompassing the major remote sensing areas. Included in the toolkit are several case studies that show the efficacy and usefulness of remote sensing.
