Ground control requirements for precision processing of ERTS images Ground control requirements for precision processing of ERTS images
With the successful flight of the ERTS-1 satellite, orbital height images are available for precision processing into products such as 1:1,000,000-scale photomaps and enlargements up to 1:250,000 scale. In order to maintain positional error below 100 meters, control points for the precision processing must be carefully selected, clearly definitive on photos in both X and Y. Coordinates...

Proceedings of the Black-footed Ferret & Prairie Dog Workshop, September 4-6, 1973 Proceedings of the Black-footed Ferret & Prairie Dog Workshop, September 4-6, 1973
Both State and Federal agencies have been working with the black-footed ferret and prairie dog during the past few years. Much of the work is not extensive enough for publication in scientific journals and is, therefore, not reported. The objective of this Workshop was to bring workers together for discussion of the current status of the two species. Each of the Conservation Departments...

A land use classification scheme for use with remote sensor data A land use classification scheme for use with remote sensor data
The needs of Federal agencies for a broad overview of national land use patterns, trends, and environmental impacts, with data inputs from both conventional sources and some of the more exotic sensors in high altitude aircraft and satellite platforms led to the formation in early 1971 of an Inter-Agency Steering Committee on Land Use Information and Classification. The work of this...
