This paper describes the application of a relatively new remote sensing tool, airbone video imagery, for distinguishing weed and brush species on rangelands. It also demonstrates the integration of the video data with global positioning system (GPS) and geographical information system (GIS) technologies. Plant species studied were wooly locoweed [Astragalus molissimus Torr. var. earley (Rydb.) Tidrestr.], blackbrush (Acacia rigidula Benth.), and huisache [Acacia farnesiana (L.) Willd.]. A conventional color camcorder video system was used to study huisache and blackbrush. A multispectral video system that acquired color-infrared (CIR) composite imagery and its simultaneously sinchronized three-band [near-infared (NIR), red, and yellow-green] narrowband images was used for the woolly locoweed experiment. Huisache and blackbrush could be distinguished on conventional color imagery, while woolly locoweed could be detected on CIR composite and NIR narrowband imagery. Quantitative data obtained from the digitized video images of the three species showed that their digital values were statistically different (P = 0.05) from those of associated vegetation and soil. Computer analyses of a NIR image of woolly locoweed showed that its population could be quantified. The integration of the GPS with the video imagery permitted latitude/longitude coordinates of weed and brush infestations to be printed on each image. Moreover, these GPS coordinates could be used in a GIS to map blackbrush and huisache populations over an extensive rangeland area and develop a digital image data base for the future reference.
