With a surface area of 68,800 kmĀ², Lake Victoria is the largest lake in Africa. More than 30 million people living around the lake in Kenya, Tanzania, and Uganda rely on the lake for everyday use. With populations increasing around the lake, run-off from various sources is negatively impacting the water quality in the lake resulting in the introduction of the invasive water hyacinth (Eichhornia crassipes). The NASA SERVIR Coordination Office at Marshall Space Flight Center, the SERVIR-Eastern and Southern Africa Hub, the Regional Centre for Mapping of Resources for Development (RCMRD), and the Makerere University Department of Geomatics and Land Management have been assessing and monitoring water quality parameters, such as chlorophyll concentration, temperature, and turbidity, for Lake Victoria using the Moderate Resolution Imaging Spectrometer (MODIS) sensor on the Aqua satellite. As a continuation of the Lake Victoria Water Resources II project from Spring 2016, this project focused on implementing an atmospheric correction and water extraction algorithm into the Surface Aquatic Vegetation Detection Toolbox (SAVDT) that was previously created. The SAVDT processes satellite imagery from Landsat 5, 7, and 8 or Sentinel-2 and results in an output shapefile that detects the location of aquatic vegetation on the surface of the Winam Gulf in Lake Victoria. This project also conducted an accuracy assessment on the SAVDT outputs using high-resolution data from World View 2 and 3. The completed SAVDT will be used to complement the partner organization's current efforts on researching and monitoring the water hyacinth.
