A method for planning and implementation of soil compacting processes using at least one soil compactor resulting in an efficient use of compactors and an improved compacting result. Under the method, a base region (B) to be compacted is defined, the relevant aspects of a soil compacting process are planned, and only then is the process implemented by moving at least compactor in the base region (B), according to the plan. The plan for the soil compacting process may include the quantity and course of compactor passes in the base region.
