BlueTopo details the depth of lake beds and seafloor beneath navigationally significant U.S. waters.
Aquaculture application: BlueTopo displays bathymetry in a layer behind a nautical chart, which provides more context to the user and encourages a deeper understanding of the seafloor. This is helpful when determining aquaculture gear type(s) that would be compatible in those areas.
