Adding what3words to Cadcorp SIS WebMap

easy

what3words can be integrated with Cadcorp SIS WebMap and accessed via a button on the map’s interface. The user can either click on the map to return the 3 word address for that location, or input three words to zoom to the location. When the user types in the first two words and any letter from the third, they‘re offered suggestions for the final word.
