Israel

The current map as of 04/04/2009. The implementation can be found here

Israel is a small country, divided between nine graticules from (29,34) to (33,35). The graticules that encompass its major population centers each have their own problems: some are almost entirely in the Mediterranean Sea, others include much of the disputed territories, and still others contain a truly staggering amount of desert. Some even contain all three. Almost all of them include some area in neighboring countries of varying degrees of unfriendliness.

As a result, some Israelis may prefer to use an alternative algorithm, which defines a polygon including the entire state of Israel so that all Israelis share the same meeting point. An implementation of the algorithm can be found here; red zones define areas that are deemed too dangerous to access. (Geohashers are encouraged to edit the red zones to help other geohashers avoid IDF fire zones, hostile settlements, etc.) In order to calculate safe points that fall within the green zone, but outside of the red zones, the algorithm uses the previous day's exchange rates, as issued by the Bank of Israel.

Important:

• You cannot claim achievements for reaching the alternative algorithm's point. It is solely used for the purpose of arranging meetups.
• If you are planning an expedition, make sure you announce it well in advance so that other geohashers will know where you are going. It's not very helpful if one geohasher is attending a standard graticule point while another is attending the alternate graticule point, especially if both are reachable on a given day!

Most recent hashes from the standard graticules

• April 20: The Jerusalem point is between Nahal Michmash and Nahal Nimrod, northeast of Geva Binyamin/Adam, West Bank.
• April 21: The Jerusalem point is in the middle of the Dead Sea, just off the coast of Ein Gedi. The Haifa point is on southbound route 667 between Maale Gilboa and Meirav.
• April 22: No reachable hashes, unless you feel like trekking four kilometers into the desert from the route 40/route 6 junction.

Past expeditions in Israel

• May 28, 2008: Haifa East graticule point was unsuccessfully reached by Ynor
• July 28, 2008: Alternative location cheat in Jerusalem by Lady Pennywhistle.
• March 17, 2009: Yerushalmi and his wife successfully reached the Beersheba graticule's hash point in Kfar Truman.
• April 10, 2009: Yerushalmi and his wife reached the Beersheba graticule's hash point near Kfar Bin Nun.
• April 13, 2009: Yerushalmi and his wife didn't even try to reach the Tel Aviv graticule's hashpoint, but somehow came close anyway.
