Most important milestone chart based upon the surveys made from navigational surveys and soundings in 1754, 1759, and 1760 by Alexander Dalrymple. This edition of Dalrymple's map was published by his friend and French colleague, Jean-Baptiste D'Apres de Mannevillette in his later editions of Neptune Orientale.

D' Après de Mannevillette (1707-1780) was a famous French sailor and hydrograph. During a voyage to China in 1728 he succeeded in correcting the latitudes of many places using new instruments. Back in Franc he devised a plan to correct and publish all the existing maps of the route to China: the Red Sea, the coasts of India, Malaya, the northern parts of Indonesia, Indochina and China.
When the first edition of his Atlas Le Neptune Oriental (containing only 22 charts) was published in 1745, it was regarded as a major achievement and a library indispensable to navigators. In 1672, d'Après was appointed director of an office established by the Compagnie des Indes for the publication of charts.
