Error estimation for gridded bathymetry [PDF]

open access: yes2015 IEEE Applied Imagery Pattern Recognition Workshop (AIPR), 2015
Estimating the uncertainty or predicted accuracy of gridded products that are generated from historical bathymetric survey data is of high interest to the maritime navigation community. Surface interpolation methods used for gridding survey data in practice are well established. This paper investigates error estimation methods for gridded bathymetry in
