A Well-Known Text (WKT) representation of the shape (footprint, geometry) that defines the Location. A Location may have both a point-radius representation (see decimalLatitude) and a footprint representation, and they may differ from each other.

`POLYGON ((10 20, 11 20, 11 21, 10 21, 10 20))` (the one-degree bounding box with opposite corners at longitude=10, latitude=20 and longitude=11, latitude=21)
