Each section contains an illustrated summary of...
Mapping the Earth from Space

Every few years, new satellite images of the earth's surface are acquired from remote sensors aboard a space craft. Because the technology associated with satellite imagery improves so rapidly, these new images generate a wave of excitement throughout the scientific community, representing an opportunity to view the earth's surface at a level of detail (resolution) and accuracy never achieved...
