GIS based soilinformationsystem (SIS) is very important for assessment of the capacity of land production, the status, rates of soil degradation and global change studies.
In the soil resource management informationsystem based on GIS, the most basic operations are the operation of map, the attribute data inquiry and statistics and spatial data inquiry as well.
The design principles, system structures, system functions, system characteristics and operation environments of Agricultural Soil Water Engineering Informationsystem (ASWEIS) have been introduced.
