A characterization of the data, including its intended use and limitations.
Land cover for the Snake River Plain.
To show what land is under agriculture in the Plain and, if it is irrigated, the method of application sprinkler vs. gravity.
Procedures_Used: USGS 1:24000 scale quadrangle maps were reduced to 1:40000 scale to match 1987 aerial photography. These photos were then interpreted and land cover was compiled and transferred to the photo-reduced quads. The quad maps with the codes, linework, and attributes were digitized in the Universal Transverse Mercator Zone 11 or Zone 12 in pcARC/INFO 3.4.1 with an RMS of no greater than 0.003. Checkplots were made and checked against the maps from which they were digitized to ensure quality and consistency and to check for technician error. They were then field checked against randomly sampled areas in 1992. Dewayne made some revisions in 1996 and original areas were changed and some areas were added. Dewayne made some revisions in 1997 to areas north of Arco, and to a lesser extent around Bruneau and eastern Caribou county. Revision 1 was initial compilation of data. Revision 2 was made after checkplots were made. Revision 3 made after field checks. Revision 4 is the final version after the 1996 additions. Revision 5 is the final version after the 1997 additions.
