Land features are almost completely devoid of topography or relief; coastline augmented with hachures. Depth is shown by soundings.

According to Burden (230) this is the earliest map to show the correct north-south orientation of Lake Champlain and to represent Prince Edward Island accurately. It is considered one of the most important maps of the region of the early 17th century. It is interesting to note the different languages used: the cartouche is Latin, most place names are French and the cardinal points in the margin, Dutch.
This map contains elements from previous maps; most specifically, the cartouche is copied from De Vaugondy's 1755 map of Canada. The map is hand coloured with the colours showing the British and French possessions of the area covered. The atlas this map is from was published between 1776 and 1784. Sources consulted do not specify which printing this map is from although as the 1st state it was earlier, rather than later in this period.
"Cette carte à été dressée les originaux conservés au Dépôt des plans de la marine. Le Port Dauphin, la rade de Ste. Anne, et la baye de Niganiche ont été levés, en 1733, par M. Boucher, ingenieur du roi, l'entrée de Labrador l'avoit été, en 1722, par M. le cher. de L'Etanduere. On à réduit ces deux Plans à la même Echelle, pour les présenter ensemble sur une même Feuille." Translation (not literal): This map was drawn from originals stored at the Dépôt des plans de la marine. Port Dauphin, St. Anne's harbour and Niganiche bay were surveyed in 1733 by Mr. Boucher, engineer to the King, The entrance to Labrador was done in 1722 by Mr. de L'Etanduere. We reduced the two maps at the same scale, to present together on the same sheet.
The atlas this map is from is a typical example of a lot of atlas publications in the 19th century. Plates were used and reused by publishers over the course of many years and were transferred from one publisher to another with no, or very minor, changes. When a map is detached from its' atlas it becomes difficult to verify which atlas a map is from. Only by comparing it to known versions can conclusions be drawn. In this example, Greenleaf reissued an 1836 atlas of the same name by David Burr and at least 4 known versions were produced.
The 1836 publication of this atlas was the 1st edition. Virtually identical maps, with the exception of the publication information, appear in subsequent editions and atlases by Mitchell and others. The publication statement and the color palette definitively tie this to the 1836 publication.
