DESCRIPTION: This large-scale antique hydrographic chart of the town and environs of Gravelines is a fine example of the work of Charles-François Beautemps-Beaupré (1766-1854). Beautemps-Beaupre was one of the earliest hydrographers to use isobaths to represent water depth. In this chart he uses differently colored isobaths to represent three depth categories : less than 10 feet ; between 10 and 16 feet; and between 17 and 24 feet. This detail along with numerous soundings demonstrates Beautemp-Beaupre's dedication to his profession, and is the reason he is sometimes referred to as the 'father of French hydrography'.
Date of 1802 is consistent with a dedication to vice-admiral F.E. de Rosily who served as Directeur of the Depot Generale de la Marine from 1795-1805.
