Development of quick graphics traceability system for agricultural products

Quick graphics traceability of agricultural products is an important means, which can ensure the reliability of traceability process, enhance the visibility of traceability results and improve the public participation. A traceability flow was designed based on the trace coding method with geographical coordinates and multiple encryption and display tool of Google Earth. Its mainline was composed of correctness validation, trace code analysis, production area orientation, attribute tracing and result display. Then, a quick graphics traceability system for agricultural products was developed with Browser/Server (B/S) structure, by adopting .Net platform and calling Google Maps API. The system was used in the Supervision and Management Platform for Agricultural Product Quality Safety in Guangzhou. The results showed that this system reflected the characters of graphics tracing and quick orientation to improve the traditional traceability system. The system is favorable for extending the application of traceability systems and the management of emergency incidents for agricultural product quality safety.
