Then we established a spatial data storage model, which has unified the data standards and achieved the management of spatial data and attribute database. Taking ArcGIS API for iOS as GIS platform, Xcode as the tool, we have realized the functions of data integration, data query, data statistics and fertilization recommendation, and constructed the management and service platform of mobile fertilization expert system.展开更多
