Between about 1675 and his death in 1703, he was based under the sign of the Atlas at premises in Cornhill and New Cheapside, London. His cartographical output was large and varied. His best-known maps are those first published in a new edition of William Camden’s "Britannia" in 1695, and subsequently reissued in 1722, 1753 and 1772. These maps were manly based on Christopher Saxton’s maps produced in the 1570s but were updated by new information from gentlemen of each county, and were newly engraved. Each had a decorated cartouche, and showed numerous place names. In 1701 Morden also produced a series of smaller county maps often known as ‘Miniature Morden’s’.

In contrast to earlier maps, Morden’s are less highly decorated, and simplified, concentrating on clarity and clear presentation.  Apart from a few early copies of the 1695 edition, the maps were published uncoloured.  Maps found coloured today were coloured at a later date, often during the 19^th or early 20^th Century.  This map is from the 1695 first edition of 'Britannia'.
