Research on Farmland Information Collecting and Processing Technology Based on DGPS

In order to realize the farmland information pinpointing acquisition, this paper has conducted the technology research for farmland information collecting and processing based on the DGPS. According to the precision agriculture’s demand which agricultural condition information should be made positional, fast, precise, continuous acquisition, system uses the DGPS receiver and the touch-screen computer, uses Microsoft Access database and uses Visual Basic 6.0 to establish the application program, which used in the farmland information acquisition and processing. According to the farm land contract's demand, the method is established by using DGPS receiver to survey and drawing for field length of side and the area, which was applied in the farm and the effect was good. The result shows that this technology had very good usability.
