Title: Land Use & Land Cover, 1980, Snake River Plain, Idaho
Originators: Idaho Department of Water Resources
Publisher: Idaho Department of Water Resources
Publication place: Boise, ID
Data type: vector digital data
A characterization of the data, including its intended use and limitations.
Land use data of the Snake River Plain developed using image processing of 1980 Landsat MSS data. Developed as part of the Regional Aquifer Systems Analysis (RASA). The emphasis was to map irrigated land use. See the following report for details of the project. Hal Anderson, 3/18/83, "1980 Inventory of Irrigated Cropland of the Snake River Plain".
Land use and land cover data for RASA.

The original geocorrected classification files were visually overlayed on Landsat TM data to check for spatial accuracy. Areas of scenes did not register well so we decided to redo the geocorrection using programs in ARC/INFO. The five original classification files were geocorrected using control points selected from Landsat TM data. The control points were selected in ArcView and the classifications were geocorrected using GRIDWARP in ARC/INFO. The output projection was IDTM (Idaho Transverse Mercator). The ouput pixel size was 57 meters. The five files were mosaicked using MERGE. The final ouput file is rasa80lc. (The original name was rasa_all).
