New papers related to remote sensing of the earth

Worldwide experience of many individuals and organizations with remote sensing data acquired from space, primarily Landsat-1, -2, and -3, has demonstrated its utility for land use classification, agricultural assessment, energy and resource exploration, and many other applications. There has been some reluctance to adopt these systems in operational programmes because of a lack of assured continuity of data collection, continuing changes in the systems, and some dissatisfaction with the types of data made available to users. Nevertheless, there is sufficient conviction of the value of satellite remote sensing so that new systems will be developed by several countries in the decade of the 1980's. The status changes continuously as studies are completed, and budgets are adjusted. This review presents the situation at the beginning of 1982.
