Spatial Decision Support System for Precision Farming Based on GIS Web Service

As the next generation GIS technology, GIS Web service is able to effectively cope with several problems of traditional GIS applications, such as hard to update old systems, lacking of good interoperability and hard to integrate with other systems, etc. This paper studied how to construct a spatial decision support system (SDSS) for precision farming based on GIS Web service. Main components of the system and the decision workflows were discussed in the paper. As examples, precision fertilization and precision irrigation were used to explain key technologies of the SDSS construction based on GIS Web service. The research result shows that GIS Web service is suitable for developing spatial decision support system for precision farming, and GIS Web service based applications has obvious advantages in dealing with problems such as sharing spatial data, software reuse and reducing the cost of system integration.
