摘要：Modeling of watersheds greatly benefits from high spatial resolution of soil data. The models need to be compatible with a format in which soil data is delivered. In the United States, the Soil Survey Geographic (SSURGO) database provides higher-spatial resolution soil data, but AVSWAT and ArcSWAT, two GIS-enabled interfaces for preparation of input data and post-processing for the Soil and Water Assessment Tool (SWAT), are compatible only with the State Soil Geographic (STATSGO) database which is normally prepared with 10 to 20 times coarser scale. Available SSURGO processing tools currently work with AVSWAT, but not with the latest version of ArcSWAT. This study developed a utility for ArcMap GIS that is capable of processing SSURGO soils data into a modified STATSGO format that is readable by ArcSWAT. The SSURGO-ArcSWAT utility was tested for regional soil misclassification in the state of Kansas.
