| This article in view of the Inner Mongolia autonomous region of hydraulic erosion census work in the industry met some key technology problems of research and analysis, and put forward corresponding solutions to problems. Including:(1) In the first phase, the water erosion census material preparation stage, through the use of R2V software, and ArcGis software ArcScan module of water erosion survey of vector unit for reproduction vector of two methods of contrast, discuss the water erosion field investigation unit for reproduction process of making use of ArcScan module that vector is more scientific and reasonable.(2) According to the field collection back water erosion field investigation unit qing drawing, may appear all sorts of uncertain conditions, the author discusses three different scheme registration to the difficulty of the way, and analyzes its accuracy, selecting the best program, complete the water erosion field investigation unit made qing drawing.(3) The autonomous region in the complex terrain of hilly-gully loess, the channel number, inconvenience to the artificial erosion gully for interpretation, through the two kinds of remote sensing interpreter of the comparison of the way. using remote sensing image and the way of the combination of the DEM, discusses choose interpretation methods of few steps, simple operation, intervention of less software and method, through the analysis that by use of the DTGIS erosion gully census platform is a better method to deal with. |
