The traditional desktop-based fertility evaluation was affected by the frequently updated data,the complex operations and so on.The impact was difficult to obtain real-time evaluation results.According to the workflow technology and Open Geospatial Consortium (OGC) specification,a method was proposed to achieve fertility evaluation in the network environment.All data acquisition and processing functions in this method are packaged into OGC-compliant services.By calling the service-related operations,each operation will be converted to comply with OGC standard’s activities in workflow platform.In this way,it will be able to realize automatic processing function connecting the operation activities.In order to verify the method,the soil data of Honghuatao Town in Yidu City,Hubei Province was used as an example to achieve soil fertility evaluation under the network environment.The example deployed all soil data into data services and procedures related to fertility evaluation into WPS services.The results showed that the combination of the geographical information service with the workflow technology could realize the fertility evaluation under the network environment and improve the efficiency of the fertility evaluation.
