NetworkDataTExtrapolationDistance Property

Distance from span/gridpoint where extrapolation takes place, i.e., if location chainage is outside the network value chainage span, but less than ExtrapolationDistance from the span, then the nearest value is extrapolated. Set to 0 to disable. Default is zero. Can not be negative.

When CanInterpolate is false, this specifies the distance to a chainage value/span that will return the point/span value, a tolerance value.
