Simplification of the Ground creation by grids

More and more ground are grids (ASC Format) with millions of points. A new parameter was added to optimize MithraSIG ground creation. This new Z accuracy parameter reduces the number of ground points with a very limited lack of precision.

It reduces points considering a maximum tolerated gap between the initial data and MithraSIG ground. An altitude comparison is done for each point between a complete data triangulation and an approximate triangulation while remaining inside the tolerance.

The result thus obtained represents the ground feature points: thalwegs, crests (mounds), summits, hollows, break points (banks).
