Technical Abstract: Aquatic and wetland weeds are a serious management problem in many freshwater ecosystems of the world. This paper presents an overview on the application of using high resolution QuickBird multi-spectral satellite imagery for detecting weeds in waterways and wetlands in Texas. Unsupervised image analysis was used to classify false color composite (green, red, and near-infrared) satellite images of weed infestations and accuracy assessments were performed on classified images. Plant species addressed include giant reed (Arundo donax L.), waterhyacinth [Eichhornia crassipes (Mart.) Solms], spiny aster [Leucosysris spinosa (Benth.) Greene] , and giant salvinia (Salvinia molesta Mitchell).
