Interpretive Summary: Giant salvinia is one of the world’s most noxious aquatic weeds. Researchers employed airborne digital video imagery and an unsupervised computer analysis to derive a map showing giant salvinia and other aquatic and terrestrial features within a study site located in northeast Texas. The map had a user’s accuracy of 74.6% for the giant salvinia class, indicating aerial digital videography has potential as a tool for differentiating giant salvinia from other terrestrial and aquatic features. Natural resource managers can use the thematic map as a decision support tool.
