Design and Implement of Information Display Platform for Agricultural Technology Extension in Fujian Province

According to four regional particular agricultural industries（i.e. tea，vegetables，edible fungi and regenerated rice）of Fujian Province and new organic combination mode of “scientific experiment base，regional demonstration base，grassroots promotion site and farmers”adopted in agricultural technology extension（ATE）service，an information technology service system for ATE were designed and proposed.To address issues of multiple types，multiple themes，multiple sources，and heterogeneities of data related to new ATE information service，a unified information resource classification and coding strategy was adopted.With use of coding strategy，a“GIS+mode”display system and its back-end management tool for ATE was designed and implemented based on the ASP MVC architecture of the.NET framework.This system associated various data with WebGIS map layers according to resource classification codes，was deployed in a scalable and migratable H3C CAS cloud platform，supporting access and management of Internet of Things（IoT）monitoring equipment.It supported hierarchical control and integrated display of technical service information of multiple industries，which realized dynamic management and presentation of 14 064 records with 16 agricultural themes and real-time monitoring data of related scientific research test base，etc.Various types of data（such as video，pictures，text and so on）were stored in the system（about 75GB），which could provide convenient and efficient services for enterprises，farmers and so on.
