Light Reflectance Characteristics and Remote Sensing of Waterlettuce
Waterlettuce (Pistia stratiotesL.) is a free-floating exoticaquatic weed that often invades and clogs waterways in thesoutheastern United States. A study was conducted to evaluatethe potential of using remote sensing technology to distinguishinfestations of waterlettuce in Texas waterways. Fieldreflectance measurements showed that waterlettuce hadhigher visible green reflectance than associated plant species.Waterlettuce could be detected in both aerial color- infrared(CIR) photography and videography where it hadlight pink to pinkish-white image tonal responses. Computeranalysis of CIR photographic and videographic images hadoverall accuracy assessments of 86% and 84%, respectively. (PDF contains 6 pages.)
