Point Radius Spatial Fit

A term from the Darwin Core standard:

The ratio of the area of the point-radius (dwc:decimalLatitude, dwc:decimalLongitude, dwc:coordinateUncertaintyInMeters) to the area of the true (original, or most specific) spatial representation of the dcterms:Location. Legal values are 0, greater than or equal to 1, or undefined. A value of 1 is an exact match or 100% overlap. A value of 0 should be used if the given point-radius does not completely contain the original representation. The dwc:pointRadiusSpatialFit is undefined (and should be left empty) if the original representation is any geometry without area (e.g., a point or polyline) and without uncertainty and the given georeference is not that same geometry (without uncertainty). If both the original and the given georeference are the same point, the dwc:pointRadiusSpatialFit is 1.
