XYZLocationSpanCreateSubLocationSpan Method

Creates a sub-locationSpan defined within chainage interval. Derived data is automatically adjusted to match locationspan The chainages must lay within the span.

If an existing coordinate is inside but very close to one of the new locationspan end points, that coordinate will not be part of the new span, hence you may not find all points of the existing span in the new span. It uses LOCATION_EQUAL_TOLERANCE on the M value.
