Creator_Of_Source:
ERS-1 SAR: Radarsat International, Richmond, British Columbia; Rectification was per-
formed separately by Dept. of Geological Sciences Remote Sensing Laboratory, Dartmouth
College, Hanover, NH (Omaha, Chester and Sioux City scenes) and by Dept. of Energy
Pacific Northwest Laboratory, Richland, WA (remaining scenes).
Landsat TM: Earth Observation Satellite Company (EOSAT), Lanham, MD
SPOT Panchromatic: SPOT Image Corporation, Reston, VA
Data_Set_History: 1. Imagery was rectified using UTM data with the following datums: TM
-> NAD27, SAR -> NAD27, SPOT -> WGS84.
2. Vector data was screen digitized and imported to ARC/INFO using `generate' with the
`line' command.
3. Projections were assigned to each arc coverage using `projectdefine'. For the purposes of
this data set, WGS84 was defined as NAD83.
4. The NAD27 data were transformed to NAD83.
5. The Omaha and Chester coverages were clipped to contain only the region within the
UTM Zone to which their images were rectified.
6. Coverages were converted to DLG-3 Optional using `arcdlg'.
