Jordan Transverse Mercator (JTM) () is a projected coordinate system defined by the Royal Jordan Geographic Center (RJGC). This system is based on 6° belts with a central meridian of 37° East and a scale factor at origin (mo) = 0.9998. The JTM is based on the Hayford ellipsoid adopted by the IUGG in 1924.
No transformation parameters are presently offered by the government.Grids & Datums—Hashemite Kingdom of Jordan Article by Clifford J. Mugnier, C.P., C.M.S. However, Prof. Stephen H. Savage of Arizona State University provides the following parameters for the projection:
Prof. Savage also offers software, ReprojectME!, which will convert coordinates between JTM and other systems. (See http://daahl.ucsd.edu/gaialab/# for more information.)
The central meridian of 37° East is roughly midway between the extremes of Jordan: the Karameh Border Crossing with Iraq is close to 39° East, while the city of Aqaba on the Red Sea is close to 35° East.
