Development of an automatic farm works recording system using GPS

We have been developing an automatic farm works recording system to visualize the work costs. It was difficult to record farm works exactly in a small area. We have developed a new method to identify the working location using the moving speed of the worker, also combining the in and out information to a greenhouse with a GPS location information. We conducted experiments on recording farm works by the proposed system in a farm fields and greenhouses. This report shows the new methods for recording farm works and the results of the experiments.
