About: 1840–41 Royal Engineers maps of Palestine, Lebanon and Syria

The 1840–41 Royal Engineers maps of Palestine, Lebanon and Syria was an early scientific mapping of Palestine (including a detailed mapping of Jerusalem), Lebanon and Syria. It represented the second modern, triangulation-based, attempt at surveying Palestine. It has occasionally been mislabeled as an Ordnance Survey map; in fact none of the officers worked for the Ordnance Survey, which was a separate organization. The Ordnance Survey of Jerusalem, carried out almost 25 years later, was a separate and materially more detailed endeavor.
