摘要
坡度是描述地表形态的基本指标。利用ArcGIS软件对已有的1∶10 000 DEM数据进行坡度分析,能够正确高效地识别地形特征,确定对应图幅所属的地形类别。研究成果已正式应用于河北省第一次全国地理国情普查和其他测绘地理信息管理工作。
Slope is the basic indicators of describing the earth ’ s surface .Using the software of ArcGIS to slope analysis with given 1∶10 000 DEM data can identify terrain characteristics correctly and efficiently .And it will determine the terrain type of corresponding topography .The research results have been formally applied to the first national geographic conditions census of Hebei province and other surveying and mapping geographic information management .
