LANDSAT Fly Over Land Use Data for the Chesapeake Basin
Listed in NASA Earthdata CMR
In order to create a model to estimate nutrient loadings, the Chesapeake Bay Program obtained LANDSAT satellite images to map land use of the Chesapeake Basin.
Description
The data was aggregated into sub-basin units and divided into nine categories of land use: forest, cropland with winter cover (low-till), cropland without winter cover (hightill), pasture, low density residential, medium density residential, high density residential, commercial industrial, and idle land.
Photographs were taken in April, May and June 1977-1979, to determine differences in agricultural use. (VAMDSG). Processing: LANDSAT imagery USGS Level I Land Cover Classification analysis was performed on Eastern Regional Remote Sensing Application (ERRSAC) Hewlett-Packard 3000 computer at Goddard Space Center using Interactive Digital Image Manipulation System (IDIMS) and Geographic Entry System (GES) software packages.

The data are available as file LAND,SSD and can be requested from the CBP Computer Center by letter or telephone; requests which require more than three hours of staff time to complete must be approved by the EPA Chesapeake Bay Program Director; requests requiring less than three hours are completed typically in six to eight weeks; requests requiring more staff time may take two to six months, depending upon the nature of the request.
User accounts may be set up for those needing access to CBP-CC data base if the proposed work is included in the CBP Restoration and Protection Plan; accounts must be approved by the CBP Data Management Subcommittee. EPA Chesapeake Bay Program Computer Center
