Status and plans of the Department of the Interior EROS program

The Earth Resources Observation Systems (EROS) Program of the Department of the Interior has been actively participating in the LANDSAT (formerly ERTS) program and other investigations with remotely sensed data. A large number of applications have been demonstrated that can assist in the discovery of nonrenewable resources, monitoring areal extent of renewable resources, monitoring environmental change, and in providing repetitive data for planimetric revision of small-scale maps and maps showing land cover classes. A new and potentially revolutionary approach, that of "automated cartography," has been initiated through the versatile nature of the data available from LANDSAT. "Automated cartography" as used here refers to the ability to automatically extract land cover classes and relate these classes to geographic position.
