His is known to have been a surveyor for the Council of Holland and co-authored several books with Rembrantsz Dirck van Nierop. Though little is known of Vooght's life, his most important cartographic work appeared in conjunction with the prominent Johannes Van Keulen firm, with whom he partnered in 1780. Vooght was responsible for creating and compiling most of the maps in Van Keulen's seminal Nieuwe Lichtende Zee-Fakkel, with many early editions bearing only his name.
