In order to realize the digitalization and visualization of information management in agricultural-region, a VRGIS-based digital agricultural region management system (VDARMS) was developed with SuperMap 2008 as the platform of spatial information management, VRMap 3.0 as the driver of scene, and integrating with the existing knowledge model for crop management. This system realized the functio...

Agricultural pollutant runoff is a major source of water contamination in California’s Sacramento River watershed where 8500 km of agricultural land influences water quality. The Soil and Water Assessment Tool (SWAT) hydrology, sediment, nitrate and pesticide transport components were assessed for the Sacramento River watershed. To represent flood conveyance in the area, the model was improved ...

This paper presents results for an automatic navigation system for agricultural vehicles. The system uses stereo-vision, inertial sensors and GPS. Special emphasis has been placed on modeling the natural environment in conjunction with a fault-tolerant navigation system. The results are exemplified by an agricultural vehicle following cut grass (swath). It is demonstrated how faults in the syst...
