The Survey of Palestine was the government department responsible for the survey and mapping of Palestine during the period of British Mandatory Palestine. The survey department was established in 1920 in Jaffa, and moved to the outskirts of Tel Aviv in 1931. It established the Palestine grid. In early 1948, the British mandate appointed a temporary director general of the Survey Department for the impending Jewish state; this became the Survey of Israel. The maps produced by the survey have been widely used in "Palestinian refugee cartography" by scholars documenting the 1948 Palestinian exodus, notably in Salman Abu Sitta's Atlas of Palestine and Walid Khalidi's All That Remains. This composite map of the region of Palestine was assembled from twenty-four separate 1:100,000 sheets published by the Survey for Palestine and its successor, the Survey of Israel, between 1942 and 1958.Map credit: Survey of Palestine and the Survey of Israel; assembled by DutchTreat
