GeoGnomo is an open-source project exploring various forms of geocoding for use in Smart Ledgers (aka blockchains with embedded computer code). The GeoGnomo project focuses on memorable systems that provide easy ways to aggregate areas together, as well as giving users some clues to location and distance and scale. GeoGnomo consists of three systems for geostamping: Quaternary Triangular System, a Quaternary Rectangular System, and a Variable Rectangular System. Each can be used to record geographic areas into a blockchain. We have provided the source code and an online translation from latitude & longitude areas to geocodes and back. Thus, blockchain applications have almost an instant ‘global post code’ or ‘global zip code’ system. By using consistent geocoding data retrieval is easier. Users can share information easily – “tell the drone to come to QTS:F49PUR9B7-20”, a resolution of 7.6 metres.
We believe the principal qualities of a good geocode are:
|Latitude/Longitude Coordinates||Poor||Average||Very Good||Poor|
|Quaternary Rectangular System (QRS)||Good||Average||Good||Good|
|Quaternary Triangular System (QTS)||Good||Average||Good||Good|
|Variable Rectangular System (VRS)||Average||Good||Average||Very Good|
|Quaternary UTM System (QUTMS) (Experimental)||Good||Average||Good||Good|
