The docs also seem to indicate that 3mx3m is the smallest grid they can address, but at the same they use addressing in slums as a use case...who has that much

- drinckes 7y agoHi - plus codes founder here. You can just keep adding digits and the area gets smaller. The way I think of it is: +XX "house" (13x13 meters) +XXX "bathroom" (3.5x2.8 meters) +XXXX "chair" (87x56cm) +XXXXX "envelope" (22x11cm) In Kolkata the NGO (Addressing the Unaddressed) are using +XXXX codes.
- meerkat14 7y agoWait a minute. How are Kolkatans with (probably) cheap phones getting their hands on coordinates that accurate when phone GPS is usually only good to within ~5m?[1] I assume the postal workers are getting high end equipment?

- WorldMaker 7y agoFirst guess: Signs, maybe? You only need a few accurate surveyors and they could write coordinates in places. Use the cheap accuracy to get close then follow the signs. Looking up the charity mentioned, they even have a nice photo of such a sign, so my guess appears validated: https://www.addressingtheunaddressed.org/services https://www.addressingtheunaddressed.org/services Neat.
