From: Bathymetric effect on geoid modeling over the Great Lakes area
Standard devations of geoid model differences with the increasing of the Stokes’ truncation degree. 155 GNSS/Leveling benchmarks located along the shore of Lake Superior close to the state of MN are used for the validation. The geoid models are computed by using three different RTM schemes (RTM-Base: dashed lines; RTM-Condensed: solid lines; RTM-Density: plus symbols) and three gravity observation noise levels
