----------------------------Original message---------------------------- On May 13th I posted a reply to Donna Schenstom's request for information on the Palestine grid. Dov Gavish has pointed out to me that what I was referring to was a British Army transmformation of the the projection to Transverse Mercator for military use during WW II. His suggestion of contacting the Survey of Israel is then the proper one. Sorry to mislead you. I guess amateurs shouldn't walk where experts fear to tread.
