Indicates that features are moved by adding a delta vector to each of its points. This means that the feature keeps its size and shape in the coordinate reference system in which it is stored. This is efficient, but will also distort the size and shape of the object on the earth surface.

Indicates that the feature is moved while trying to keep its true size and shape on the earth surface, like Feature.MoveOnEarthAsCompass does. Actually, this would be possible on a sphere but not on an ellipsoid: if you cut a piece of shell from the top of your breakfast egg, you cannot make it fit tightly on the side of the egg. So, on the earth ellipsoid, it is not really possible to move a polygon and keep all edge lengths and interior angles exactly the same. But the tool does its best, which is usually enough. Rotation during the move is another problem, see StandardTool.CompassPoleLongLat.
