Bruni d'Entrecasteaux was fortunate in having good officers and scientists, most importantly from the exploration point-of-view the expedition's first hydrographical engineer, C.F Beautemps-Beaupré, who is now regarded as the father of modern French hydrography. The work this officer did in the field was excellent, and his charts, when published in France as an "Atlas du Voyage de Bruny-Dentrecasteaux" (1807) were very detailed. The atlas contains 39 charts, of which those of Van Diemen's Land were the most detailed; they remained the source of the English charts of the area for many years.
