The standard deviation of the bed elevation for all crossover errors for the radar data is 33.3 m. However, this value is skewed by a few high error points in regions of more extreme topography. Over areas with smoother topography the standard deviation of the crossovers is ~10 m.

Resolution: The line spacing for the main survey area is 8.8km, with tie lines 44 km apart. Additional regional lines explore specific targets. The along track sample spacing is 20 m.
