This map of the coast of French Guyana with an insert map of the mouth of the Cayenne River from 1785 was possibly produced in preparation of van Keulen’s De nieuwe groote lichtende zee-fakkel which was released in 1790. But even before the release of this atlas, these ‘Guyana’ maps left an impression. Two years after printing this series, van Keulen was assigned as one of the three commisioners of martime cartography by the Dutch Admirality. Maps like these helped in attaining this posititon. The shown soundings at sea and the notations at the bottom of the map allow the reader to find a way through the waterways on the coast of Guyana. The mangroves and sandbanks did not make this survey an easy task and van Keulen succeeds in displaying the results accurately. Relief is equally shown accurately. -North is up.
