Kartograf, från 1687 styrmansdirektör vid amiralitetet, en befattning närmast motsv. såväl generallotsdirektörens som chefens för sjökarteverket i vår tid. G. utarbetade nya författningar rörande lotsväsendet, vilka sedaan länge förblevo gällande, och upprättade och utgav tills. med sin företrädare W. v. Rosenfeldt den första svenska sjöatlasen 1694, 'General hydrographisk chart-book öfwer Östersiön', vilken s.å. även utkom i engelsk och holländsk uppl.

Geografia di M. Livio Sanuto distinta in XII libri. Venice: Damiano Zenaro, 1588.
The first printed atlas of Africa. Sannuto’s Geographia was intended as a compendium of world geography, but the project was curtailed by his death. Only the first part, devoted to Africa, was ever published, and that posthumously. Skelton describes the Geographia as a “methodical and precisely documented description of the geography of Africa” and notes the “critical sense” exercised in the compilation of the maps, engraved by Sanuto’s brother Giulio.
It is unfortunate that the work was left incomplete, as Skelton suggests it would have been “among the masterpieces of Renaissance geography”; the fact it was incomplete may help explain its rarity on the market today.
