property Location.HorizontalPrecision as Long
Specifies the horizontal precision of the data, in centimeters.

TypeDescription
Long A long expression that indicates the horizontal precision of the data, in centimeters.

The HorizontalPrecision property gives the horizontal precision of the data, in centimeters. This is the diameter of the horizontal "circle of error", rather than a "plus or minus" value. (This was chosen to match the interpretation of Size; to get a "plus or minus" value, divide by 2.) [RFC 1876]
