TheThe QBG01 gravimetric quasi-geoid model for Bulgaria covers the area from 41° to 44.5° North latitude and from 22° to 28.5° East longitude. It was computed by remove-restore technique, based on the global geopotential model EGM96 and the topographic model DTED Level 0. The maps of Bouguer anomalies for Bulgaria in scale 1:200000 were used to derive gravimetric data. Scanned images of these maps were processed with programs from Intergraph to obtain a digital grid with spacing 1 arc-minute. To compute the quasi-geoid model and to prepare data for the processing, programs from the GRAVSOFT package were used.
