The objective of this research is to develop a field irregularity modifying system using work chracteristics of harvesting and generating GIS maps based on measured terrain information. To generate a GIS map based on the work chracteristics of harvesting and terrain information, vehicle location is essential; therefore a Real Time Kinematical Global Positioning System (RTK-GPS) provided vehicle positions, and an Inertial Measurement Unit (IMU) provided direction and inclination angles, and a laser scanner provided terrain information of the field. The system was built on a robot tractor and commercial tractor. The result shown an average error of 5.2 cm and an RMS error of 2.9 cm when the laser was scanning beneath the robot tractor, which is sufficient for terrain surveying. The area where working characteristics is bad can be distinguished by the discriminant analysis using explanation variable of synthetic vector and inclination angle.
