DATA AVAILABILITY: All data received in the U.S. are in the public domain and can be (0
. purchased either as image products or as computer-compatible tapes from the Department
of the Interior's EROS Data Center, Sioux Falls, S. Dak.
The EROS Digital Image Processing System (EDIPS) will be operational by mid 1978.
High density digital tapes supplied by NASA/GSFC will be converted by EDIPS high
resolution laser-beam film recorder to first-generation master film products in
241-mm format, enabling EDC to deliver second-generation products to data users.
CCT data from HDTs will also be formatted and recorded by EDIPS,
GROUND DATA ACQUISITION STATIONS: Existing: Fairbanks, Alaska, Goldstone, Calif.,
Greenbelt, Md., in the U.S. Prince Albert, Saskatchewan, and Shoe Cove, Newfoundland,
in Canada; Cuiaba, Brazil; Fucino, Italy. Nearly completed: Shahdasht, Iran,
Agreed upon but not yet operating: Argentina, Australia, India, Japan, Sweden,
Upper Volta, and Zaire, : 8
