Guillaume de l’Isle was one of the most respected mapmakers of the 18th century, known for his commitment to accuracy and attention to detail. This is de l’Isles third map of the continent of Asia, showing the improvements in knowledge made during the first quarter of the 18th century. Arabia has been revised, with more correct topography. Thanks to Jesuit surveys, improvements have been made in the internal details of China and peninsular India has been expanded to its correct size. The northeastern part of the continent remains the least understood. Hokkaido is portrayed as part of the mainland (Terre d’Eso) and Urup in the Kuril Islands appearrs as an oversized island off the coast. (Terre de la Compagnie). Marco Polo’s Islands of Gold and Silver appear in the Northern Pacific.

The sea between Korea and Japan is referred to as the "Sea of Korea". There is extensive and interesting detail of central Asia for this early date, showing many kingdoms, including Nepal, Bhutan, Assam and Tibet.
