what3words is a location reference system based on a global grid of 57 trillion 3mx3m squares; each square has been pre-assigned a unique 3 word address. It is available in multiple languages, works offline and has built in error detection. Easier to remember & communicate, quick & cost effective to implement, this global & human-friendly system is now available across the arcgis platform. No matter where you gather and use geographic information, a simple way to refer to locations is essential. Street addressing is often inadequate & whilst coordinates are accurate they are prone to errors in transcription and communication. 3 word addresses can make your geographic information accessible to everyone.
