Elevation-bathymetry models for the Lake Superior region

New land-bathymetry and land-lake surface elevation models were produced for the Lake Superior region. The models combine Shuttle Radar Topography Mission (SRTM) topography data with lake surface elevation and bathymetry data sets for Lakes Superior, Michigan, and Huron. The SRTM data set was chosen because it spans the international border and has relatively high resolution at 30 m cell size. These data were subsequently used for aeromagnetic data processing and gravity data reduction.
