> You current home address has nothing to do with reference points either, But it does. Based on my address, you would know what city and state I am in, and in many cases even which direction in that city my street is (e.g. NW Whatever St). Then you'd know where on the street I am because 3350 is one block over from 2428. You'd also know which side of the street I am because 3350 is across the street from 3347.

But you don't know whether you need to turn left or right to go from your street to Church street. The comparison can only be done on one dimension.

Given a complete lack of an address system in rural areas, any structure is better than nothing. If you're comparing address systems by how well local proximity can be inferred from a given address, then Lat/Long is the best system because it's global without language, national or political barriers, doesn't require formal naming, and has no arbitrary designations. Open Location Codes are based on lat/long, but designed to use alphanumerics to make it easier to remember while also working interchangeably with lat/long and country designations.

  Using normal lat/long to read a map doesn't require you to do a base20 -> base10 conversion, where the characters are 23456789CFGHJMPQRVWX instead of 0123456789ABCDEFGHIJ, and where latitude and longitude are interleaved character by character, in your head.

    Again, that's not the point of an address system. You do not use this to navigate (even with proximity built-in), but to transfer location data in a compact format. I don't see why this keeps getting misunderstood. If you need to mark an area in a reliable, deterministic and politically neutral way, especially in the absence of any existing system, then this is a good option. If you need to drive your jeep to get somewhere, then continue using the lat/long that your GPS or map provides. If you need to translate between the two, then place codes make it easy because they require nothing but simple math.

    Why did they choose that offer character set? I get excluding vowels to prevent profanity, but why exclude B, and not start from zero?

      0 and 1 look like I and O, B looks like 8, and so on. They picked characters that can't be easily confused. The letters are also chosen so they won't spell meaningful words. The relevant section of the definition is short, and an interesting read: https://github.com/google/open-location-code/blob/master/docs/olc_definition.adoc#open-location-code https://github.com/google/open-location-code/blob/master/doc...
