Abstract Aiming at the current demand for soil wind erosion monitoring, a modeling software on wind erosion was present based on the GIS. Supporting by DTGIS core service platform, the new software was developed with C# language, in addition to Silverlight as the interface designing tool and light database SQLite for data storage. This system provides customers with a number of new functionalities, including GIS inquiry service, site data management, wind factor calculation, soil erosion modulus calculation, soil erosion intensity classification, temporal analysis, spatial analysis, availability of remote clients connection and simultaneous multi-spot data uploading, and so on. Furthermore, the software was successfully integrated with GIS in the new development, which supported not only the interaction during soil erosion calculating procedures, but also the display of model process results. Finally, the software can be used to make thematic maps of soil erosion modulus, classification of soil erosion intensity, conduct spatial-temporal analysis, and achieve systematization as well as visualization of soil erosion statistics management. The various characteristics will help researchers collect, analyze, and evaluate data on soil erosion, which will make the new package become a useful supplement to inventory of research tools.
