Destined for the navy, in which his grandfather Pieter Melvill van Carnbee (1743-1810) had been admiral, he had a taste for hydrography and cartography as a student in the college of Medemblik, and he showed his capacity as a surveyor on his first voyage to the Dutch Indies, in 1835.

With the assistance of documents collected by the old East India Company, he completed a map of Java in five sheets, accompanied by sailing directions, in Amsterdam, in 1842. He remained in the East until 1845, collecting materials for a chart of the waters between Sumatra and Borneo, which was two sheets that were published in 1845 and 1846.
