Field multi-source information collection system based on GPS for precision agriculture

It is the key step for implementing decision-based Precision Agriculture to collect timely the multi-source spatial-temporal variant information that influences crop production in the field. By integrating field information collection sensor hardware, the field information collecting system based on DGPS or portable GPS receiver is developed, which can gather multi-source field dynamic information with accurate position information such as field feature distribution, crop status throughout the production season, field weeds, pest and disease distribution, soil nutrient variability, as well as some attribute information of digital picture or digital video. This system can combine the processes of positioning, attribute information recording and implementation, which realize field information collection automatically.
