Calculating the excavation cost requires us to know of some parameters and basic cost units. These units are prepared by the Yharnam team in the Yharnam geodatabase in the following table:
|

The cost of removing a single tree depends on its type and is stored in the preceding table. The cost of removing 1 cubic meter of soil depends also on the type of soil. We will develop all these algorithms in the coming sections. Note that the numbers in the table are not real and are here just for the sake of example.
