1. A method of controlling an agricultural harvesting machine having a controllable subsystem configured to cut crop on a field, the method comprising:
receiving a pre-harvest indication of topography of a ground surface in a first area of the field prior to the first area being harvested;
controlling a position of the controllable subsystem to cut the crop in the first area based on the pre-harvest indication of topography of the ground surface in the first area;
receiving in-situ data from the first area of the field after the first area is harvested by the controllable subsystem;
receiving a pre-harvest indication of topography of the ground surface in a second area of the field prior to the second area being harvested;
controlling the position of the controllable subsystem to cut the crop in the second area based on the in-situ data and the pre-harvest indication of topography of the ground surface in the second area,
detecting a first depth of a furrow between a first crop row and a second crop row prior to the first crop row being harvested by the agricultural harvesting machine;
detecting a second depth of the furrow after the first crop row is harvested by the agricultural harvesting machine;
generating a compaction factor based on the first depth and the second depth; and
controlling the agricultural harvesting machine based on the compaction factor.
