Issues covered include the current sources of remotely sensed images (aerial photography and videography, as well as many of the current satellite systems); the use of computer mapping in recording information, creating new information, and combining information from a variety of sources; and, the use of global positioning system technology. The paper concludes by examining how advancing technology and managerial time and resource constraints should cause an increase in the number of people using the technology, as well as improve services provided by suppliers and reduce costs. Technical Abstract: 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. |
