Vandermaelen was the son of a wealthy industrialist who abandoned his father's business to follow a career in cartography. His goal was to produce the first atlas ever published in which every map was drawn on the same projection and to the same scale (1: 1,641,836), with each map covering an area of approximately 20 degrees of longitude (from Paris) and 6 degrees of latitude. Because of the consistent scale and projection, the maps could be joined together to form a huge globe that would measure over 25 feet in diameter. Vandermaelen had the only known globe constructed from his maps, requiring a special room for its display. It was also the first lithographic atlas ever published. There was one edition of the atlas, published in 1825-27, and the subscription list shows that only 810 copies were sold. Koeman called his Atlas Universel, "One of the most remarkable world atlases ever made. Far ahead of its time."

A detailed map of the southern portion of present-day Northwest Territories, extending from Great Slake Lake north to Lake La Martre. It is filled with information useful to fur traders and early explorers including forts, Indian lands, small lakes, rivers, and copious notations. A large note along the eastern edge indicates that this "country is frequented every year by large herds of reindeer from August to May."
