The Intelligent Farming Machine is one of the most important equipments for precision farming. GIS is an essential technology of navigation system for Intelligent Farming Machine. Using SuperMap Objects as a GIS component, a Navigation Geographic Information System (NGIS) for the Intelligent Farming Machine was developed. The system mainly consisted of a path planning and path preview module, a positioning data correction module, a trajectory and relevant navigation data saving and displaying module, and a result analysis module. To evaluate the NGIS, validation tests were performed using a rice transplant machine that has been refitted in order to adapt to the experiment. These tests took place in a paddy field including straight path, circle curved path. The test results showed that the average tracking offset error was approximately 0.1m. It was concluding that the performance of the NGIS could meet the requirements of the automatic guidance for Intelligent Farming Machine.
