south of Jerusalem. The false origin (zero point) of the grid was placed 100 km to the south and west of the Ali el-Muntar hill that overlooks Gaza city. The unit length for the grid was the kilometre; the British units were not even considered. At the time the grid was established, there was no intention of mapping the lower reaches of the Negev Desert, but this did not remain true. Those southern regions having a negative north-south coordinate then became a source of confusion, which was solved by adding 1000 to the northern coordinate in that case. For some military purposes, 1000 was added to the north-south coordinates of all locations, so that they then ranged uniformly from about 900 to about 1300. Palestine and Levant grids

grid in 1994. The Palestine grid is still commonly used to specify locations in the historical and archaeological literature.

Specifying locations

The basic way of specifying a location on the Palestine grid is to write the east-west coordinate followed by the north-south coordinate using 3 digits each. For example, the

Dome of the Rock The Dome of the Rock ( ar, قبة الصخرة, Qubbat aṣ-Ṣakhra) is an Islamic shrine located on the Temple Mount in the Old City of Jerusalem, a site also known to Muslims as the ''al-Haram al-Sharif'' or the Al-Aqsa Compound. Its initial ...

is at 172132. This specifies the location within one kilometre. If more precision is required, extra digits can be added to each coordinate; for example, 17241317 gives the Dome of the Rock to within 100 metres. Many authors separate the two coordinates with punctuation for readability purposes, for example 172-132 or 172/132.For example, the location of Khirbet esh Sheik Mohammed is given as 1417.1984 in
