Abstract: The surface elevation is changed drastically in river erosion feature area. Due to cost and acquisition device constraints, conventional seismic acquisition data is relatively sparse in vertical and horizontal physical points, and surface measurement data density is not enough to investigate the surface structure in detail. With the development of technology and application of satellite technology, the use of geographic information system can obtain more accurate DEM elevation data. Based on geographic information of river erosion feature area, and combined with the results of surface survey control points, a surface modeling is established, achieving good results.
