Landsat, Skylab, and the Earth Resources Survey Program are experiment remote sensing efforts initiated by NASA since the mid-1960s. The greatest utility of Landsat data is for the separation of forest from nonforest land on a regional basis. Skylab can be used to classify general forest vegetation types. Aircraft photography from the Earth Resources Survey Program often provides as much detail as larger scale photography. Space Shuttle is a new program that will provide remotely sensed data which may help in forest management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
