摘要：Aquatic plant infestations impede commercial and recreational traffic through navigable waterways, block ports and passenger ferry terminals, and exert dangerous damaging pressure upon transportation infrastructure. Timely, accurate information on aquatic plant distribution and density is required both by public agencies charged with the management of navigable waterways, and by private companies engaged in aquatic plant control efforts. Traditional field-based mapping and monitoring of the extent and density of aquatic plant infestation present several challenges, including inaccessibility of areas for field sampling, rapid changes in aquatic plant location, extent, and density, and budget constrain ts on field sampling and monitoring. Remote sensing technology has significant potential to aid managers in detecting infestations that may be an impediment to transportation, prioritizing areas of plant infestation for control efforts, providing detailed information on plant extent and density for estimating control costs, and for assessing the effectiveness of aquatic plant control operations. This project evaluated the ability of satellite remotely sensed imagery to map water hyacinth and hydrilla in t he lower Rio Grande River, Texas
