주의
The semantics of the measure value are user-defined but generally describe the distance along a linestring. For example, the measure value could be used to keep track of mileposts along a road.
The value of this property is null if the geography instance is not a Point, as well as for any Point instance for which it is not set.
This property is read-only.
M values are not used in any calculations made by the library and will not be carried through any library calculations.
