A crossvalidation-based comparison of kriging and IDW in local GNSS/levelling quasigeoid modelling
Reports on Geodesy and Geoinformatics, 2022 This study compares two interpolation methods in the problem of a local GNSS/levelling (quasi) geoid modelling. It uses raw data, no global geopotential model is involved.
