<div dir="ltr">I'm an engineer at Google, and I have just open sourced a geo project we've been working on for a while.<div><br></div><div>I used to work on our maps, detecting missing road networks and in my spare time mapping roads in Papua New Guinea, Central and West Africa from the satellite imagery. But without street names or addresses, a road network isn't all that useful. People can't use it for directions, because they can't express where they want directions to. After talking with colleagues from around the world, I discovered that's it actually very common for streets to be unnamed.</div><div><br></div><div>We thought that we should provide short codes that could be used like addresses, to give the location of homes, businesses, anything. If we made them usable from smartphones, we can make addresses for anywhere available to anyone with a smartphone pretty much immediately.</div><div><br></div><div>We had some specific requirements, including that these address codes should work offline, they shouldn't spell words or include easily confused characters. We wanted to be able to look at two codes and tell if they are near each other, and estimate the direction and even the distance. The codes should not be generated by a single provider, because what do you do when they disappear? Finally, it had to be open sourced.</div><div><br></div><div>Open sourcing the project was important. We wanted to allow everyone to evaluate it so that we don't go implementing something that turns out to not be useful. If it does turn out to be useful, everyone (including other mapping providers) should be able to implement it and use the codes freely.</div><div><br></div><div>I'm pre-announcing this to a couple of geo lists today, and I'll be sticking around for comments and questions.
