Abstract

The High Plains test site (fig. 1) is one of five areas selected in the State of Texas as part of the Applications System Verification and Transfer (ASVT) Project of the Texas Natural Resources Information System (TNRIS). This test site was chosen because the Texas Department of Water Resources (TDWR) needed timely information regarding water usage for irrigation in northwest Texas. The Test Plan for this project (Finley and Baumgardner, 1981) identified three objectives for the study of this test site: (1) identification of irrigated cropland, (2) definition of the spectral signature of drought-stressed vegetation, and (3) identification of broad crop categories. This report presents the results of work on the first objective, identification of irrigated cropland.
