 In 1695 De Wit began to publish a town atlas of the Netherlands after he acquired a large number of city plans at the auction of the famous Blaeu publishing firm's printing plates.Dating De Wit's atlases is considered difficult because usually no dates were recorded on the maps and their dates of publication extended over many years.Through his marriage to Maria van der Way in 1661 he obtained, in 1662, the rights of Amsterdam citizenship and was able to become a member of the Guild of Saint Luke in 1664.
