Geolocation with 3m accuracy and error correction in 10 symbols

The only advantage I see is the checksum and in my opinion it makes more sense to check the whole message and not just a pair or coordinates.

Google's open location code is relatively new and they discussed all common existing systems. One advantage of open location code is to avoid characters 0 vs O or l vs 1. https://github.com/google/open-location-code/blob/master/doc...

The EZCOD uses a base-32 encoding that equates 0, O, o, and , 1, I, i, and 2, Z, z, and 5, S, s. The real key asset that EZCOD has vs. the other common encoding systems is the ability to correct errors -- not just detect them.

Even the most basic version with one parity symbol allows you to recover 100% accuracy, if you can identify the symbol that is lost (eg. the letter rubbed off the page).

Thanks for the link; it looks like a great resource. A quick rundown of the list of "Desired Attributes" seems to match perfectly with what EZCOD provides -- with the addition of the error detection and correction.
