The sad part is that this problem was solved decades ago with grid locators like Maidenhead[1]. It's a purely mathematical conversions with no lookup tables, cover the entire world and alternate pairs of letters with pairs of digits (so no confusing or language and culture dependent words). Code becomes longer according to the required precision, so eight digits are enough for a typical city neighborhood, ten digits goes to a 30x20m block that is good for disambiguation even in the most dense urban areas. Adding more digits will work too, but that just more work. A typical location would be something like: fm19oc75hv [1] https://en.wikipedia.org/wiki/Maidenhead_Locator_System |
