Returns an approximation of the given geography instance produced by running the Douglas-Peucker algorithm on the instance with the given tolerance.

Overloads

Reduce(DbGeography, Nullable<Double>)	Returns an approximation of the given geography instance produced by running the Douglas-Peucker algorithm on the instance with the given tolerance.
