Abstract
Algae blooms have become increasingly common in many bodies of water and are occurring in more and more new locations. Past methods have relied on in-situ sampling to determine Chl-a concentrations and can be time and cost intensive. With the use of NASA’s Harmonized Landsat imagery existing methods of index calculation can be implemented, with the added benefit of an increase in temporal resolution. This increase in temporal resolution allows for more detailed spatial and temporal analysis such as hot spot analysis. Harmonized Landsat imagery was proven sufficient in spatial and temporal resolution for detection of Chl-a in small and medium lakes using indices and hot spot analysis. However, index accuracy has been proven to be an issue in this study compared to other studies using Sentinel 2 or Landsat imagery.
