“…These systems use traditional optical scanners and relatively new sensors such as Synthetic Aperture Radar (SAR) and Microwave Scanning Radiometers (MSR) to collect information. The addition of radar and microwave systems provides resource managers with additional information that can be used to evaluate geophysical variables, such as soil moisture and terrain Orwig et al, 1995;and Wever and Henkel, 1995).…”

Researchers and managers have used remote sensing to evaluate rangelands since the late 1930's. Images have provided managers with information concerning weed detection and mapping, grazing impacts, and production estimates. However, the available data have not been fully exploited. Two newer technologies, geographic information systems (GIS) and global positioning systems (GPS) greatly enhance the utility of remote sensing products. When used in combination, GIS, GPS, and remote sensing technologies provide the spatial framework, data analysis, and location assessment tools needed to combine information sources, create new information, validate results, and provide visual representations of the spatial dynamics for an area. This paper provides a brief review of remote sensing, GIS, and GPS and attempts to develop some insight into how these technologies are developing to meet the needs of field managers as we approach the 21st Century.

Abstract. Geophysical applications of radar interferometry to measure changes in the Earth's surface have exploded in the early 1990s. This new geodetic technique calculates the interference pattern caused by the difference in phase between two images acquired by a spaceborne synthetic aperture radar at two distinct times. The resulting interferogram is a contour map of the change in distance between the ground and the radar instrument. These maps provide an unsurpassed spatial sampling density (---100 pixels km-2), a competitive pre-
