5 years ago I wrote Rgeo, a small Go package for reverse geocoding (you input some coordinates, it gives you information about the location). Today I am putting the projected on an indefinite hiatus.

Rgeo is a fast, simple solution for local reverse geocoding, Rather than relying on external software or online APIs, rgeo packages all of the data it needs in your binary. This means it will only ever work down to the level of cities , but if that’s all you need then this is the library for you.
