System for measuring and interpreting a force

A system for controlling agricultural operations comprising:

• at least one agricultural working means for working on an agricultural field;
• at least one first imaging device located at the agricultural working means for acquiring images of an environment of the agricultural working means, wherein the at least one first imaging device is adapted to provide optical data;
• a position unit for determining the absolute position of the at least one first imaging device, wherein the position unit is adapted to provide position data;
• a data processing unit comprising a data interpretation unit for interpreting optical data received from the at least one first imaging device in relation to position data received from the position unit, wherein the data interpretation unit is adapted to calculate interpretation data based on the received data;
• a mapping unit for providing a map of data based on the interpretation data,
• wherein the data processing unit further comprises:
• a feature detection unit for detecting at least one feature of an image of the at least one first imaging device;
• a feature location determination unit for locating said detected feature in the map of data;
• a feature determination unit for determining attributes of said detected feature relevant for agricultural operation of said detected feature.
