'TIMS' THERMAL-INFRARED ANALYSIS OF SELECTED LANDSCAPE PARAMETERS: THE NEBRASKA SANDHILLS.

This paper presents results obtained from a preliminary analysis of thermal emittance data gathered by NASA NSTL's Thermal Infrared Multispectral Scanner (TIMS). Digital and analog TIMS data were used: to classify multichannel thermal emittance data into broad land-cover categories, to characterize the general form and structure of surface topography, to detect minor variations in selected surface soil parameters, and to conduct a cursory hydrologic evaluation of the thermal dynamics of Sandhills lakes and associated wetlands. Results indicate that there is a significant overall potential for TIMS data in investigating a variety of landscape parameters associated with the Nebraska Sandhills.
