distance (with strategy)

Calculate the distance of two geometries using the specified strategy.

The free function area calculates the area of a geometry. using the specified strategy. Reasons to specify a strategy include: use another coordinate system for calculations; construct the strategy beforehand (e.g. with the radius of the Earth); select a strategy when there are more than one available for a calculation.
