what3words enables infrastructure organisations – including local authorities, energy, utility and construction companies – to communicate precise locations quickly and easily. This makes it more efficient to locate teams, assets, sites and services. It also enables more efficient incident reporting, and improves health and safety.
what3words addresses are a human-friendly way of giving the same information as 16 digit GPS coordinates:
