The workflow technology was tentatively applied to the terrain factor extraction. The authors chose the extensible markup language (XML) as modeling language to study and model the process of terrain factor extraction. A set of models and modeling methods suitable for terrain factor flow extraction was formed by structured organization and description of the relationship between data transfer, input data, output data, parameters, factor model and driven execution from terrain factor extraction. The model with 5 m×5 m resolution based on traditional terrain factor algorithm automatically extracted terrain factor from DEM data of the experimental area, with good results achieved. At the same time, the river network extraction was conducted to test the terrain factor extraction model. The results show that the model has strong adaptability and scalability.
