Interpretive Summary:

Technical Abstract: This paper presents an overview on the application of aerial videography with global positioning system (GPS) and geographic information system (GIS) technologies for natural resource management. Applications demonstrated include detecting and mapping: (1) Big Bend locoweed (Astragalus mollissimus var. earlei Tidestr.), blackbrush acacia (Acacia rigidula Benth.), and huisache [Acacia farnesiana (L.) Willd.] infestation on rangelands; (2) saltcedar (Tamarix chinensis Lour.) infestations in a riparian area; (3) black mangrove [Avicennia germinans (L.) L.] populations in a coastal region; and (4) citrus blackfly (Aleurocanthus woglumi Asby) infestations in an agricultural area. Video imagery (color-infrared and normal color) could be used to detect insect and plant infestations/populations. The integration of a GPS with the video imagery permitted latitude and longitude coordinates of insect and plant infestations/populations to be recorded on each image. The GPS coordinate were entered into a GIS to map insect and plant infestations/populations on a regional scale. The integration of videography, GPS, and GIS are valuable tools that can enable resource managers to develop maps showing the distribution of insect and plant infestations/populations over large areas. The digital video imagery can serve as a permanent geographically located image data base for monitoring future contraction or spread of insect and plant infestations/populations over time.
