Alaska national hydrography dataset positional accuracy assessment study
Initial visual assessments
Wide range in the quality of fit between features in NHD and these new image sources.
No statistical analysis has been performed to actually quantify accuracy
Determining absolute accuracy is cost prohibitive (must collect independent, well defined test points)
Quantitative analysis of relative positional error is feasible.
