基于DEM数据的云台山地区夷平面信息提取研究

Research on the information extractionin yuntai mountain planation surface based on the data of DEM

基于美国SRTM-DEM数据,在ARCGIS软件平台下,通过对SRTM-DEM数据的挖掘处理,利用统计学思想在matlab软件支持下确定出最佳窗口为5×5,利用最佳窗口分析并提取出地形起伏度与坡度在各个高程面下的分布情况,根据地形起伏度与高程的关系和坡度与高程的关系来判断云台山地区夷平面的分布情况;研究结果也很好地提取出了云台山地区太行期夷平面的分布范围。

Based on the United States SRTM-DEM data with the ARCGIS software platform, processing the SRTM-DEM data, with the software of MATLAB＇s support, calculating the best window for the research is 5×5, and then use the best window analysis the distribution of extracts relief degree and slope in various height surface, then according the relatianship between topographic relief degree and the elevation and the relationship between the elevation and slope to extract the yuntai mountain planation surface information; The results of the range of the height distribution of the study is also precisly which extracted from yuntai mountain in the period of Taihang.
