ABOUT THE PROJECT
In 2017, together with EOMAP, C-MAP, a leading supplier of digital navigation products to the maritime market, launched EcoSat, a new semi-automated wetland and coastal habitat mapping product that is part of the BioBase Cloud Mapping Platform. EcoSat uses the unique reflectance properties of vegetation and sea bottoms from very-high resolution satellite imagery and creates distinct polygon objects with spatial properties like area and perimeter.
For five lakes in Florida – Lake Istokpoga, Lake East Tohopekali, the northwestern marsh of Lake Okeechobee, Lake Orange and Lake Kissimmee – EOMAP delivers vegetation maps using (very-) high resolution data from WorldView, GeoEye, Pleiades and Sentinel-2 satellites to the Florida Fish and Wildlife Conservation Commission (FWC). The output of the supervised Random Forest classification, that is based on a few ground control points for classifier training, covers almost 20 distinct species of wetland macrophytes. As the classifier is developing, less training points are necessary each year and the mapping of vast and inaccessible areas can be performed with only very little sampling effort.
