NASA Hydrilla Mapping

     Using satellite imagery from the Landsat 8 Operational Land Imager, NASA researchers created a "rapid assessment tool... to map the extent of hydrilla and predict future spread throughout the SEUS (south eastern United States) by quantifying biomass through a time-series analysis. 

      The data obtained was then compared and refined against images collected from unmanned aerial systems, with the model developed being validated by in situ biomass measurements.
