To map the bryophyte's distribution, depth range, acoustic backscatter intensity, and derived bathymetric index grids are used as inputs into a hierarchical decision-tree classification model. Observations of the presence or absence the bryophyte mat from the lake floor video were used as controls for the model. The final map was converted into ERDAS Imagine (.img) and geoTIFF (.tif) formats.
