Technical Abstract: Over the past decade interest in the application of video imaging technology for remote sensing has greatly increased. The U.S. Department of Agriculture (USDA), Agricultural Research Service (ARS), Remote Sensing Research Unit (RSRU) at Weslaco, Texas has designed and assembled several video systems and demonstrated the potential and versatility of videography for natural resource assessment. This paper presents an overview on the application of video remote sensing by the RSRU, with special emphasis on agriculture and rangeland management. Multispectral black-and- white (B&W) video with visible/near-infrared (NIR) sensitivity, color-infrared (CIR), conventional color, and B&W mid-infrared (MIR) video have been used to detect or assess a variety of ecological ground variables including plant communities and species, phytomass levels, nutrient deficiencies, alfalfa root rot infestations, soil drainage and salinity, water pollution, and insect infestations. The digitization, computer processing, and integration of videography with global positioning system and geographic information system technologies also has been demonstrated. Current research on development of high resolution digital video imaging systems is addressed.
