【Abstract】 The GIS function and technique characteristics are introduced. With Client/Server and Browser/Server structure, the paper developed the soil information system based on GIS by using MapInfo to manager spatial data and SQL Server attribute data. The system realizes the inquire, retrieve and statistical analysis of soil fertility and classify information. The function of thematic map making, output and renew are also supported. The system does good to make better use of soil information.更多还原
