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, finding a hash that is reachable and safe can be difficult. It is literally impossible for all four of Israeli's major graticules to come up with reachable hashes on the same day; virtually impossible for three; and only occasionally for two. On most days, only one of the four hashes is in safe territory. Sometimes there are none.

Some Israelis may therefore prefer to use an alternative algorithm, which defines a polygon that hugs the borders of the state of Israel. 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. However, even this algorithm has its problems, because many hashes end up in desert areas, and because many safe areas are outside of the standard borders of Israel.

In summary, geohashing in Israel is tough, and any points should be evaluated for political safety first and technical reachability second. This page will chronicle the reachable hashes for Israelis on any given day.

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 29: The Haifa point is just southeast of Tuba Zangariya. So much for an accessible Independence-Day hash...
  • April 30: The Beersheba point is in fields south of Talmei Bilu.
  • May 1: The Tel Aviv point is in fields northwest of Ahituv.
