资源简介:
数据包含云南鲁甸地区地震灾区高程、坡度坡向、地貌类型数据等。(1)1:400万地貌数据是追踪收集和整理李炳元主编的“中国地貌图(1:400万),由地貌图扫描配准,在ArcGIS支持下矢量数字化得到。(2)Dem数据集由SRTM数据经拼接、投影转换、裁切得到。坡度坡向数据是在dem数据基础上利用ArcGIS空间分析模块计算得到
The dataset includes elevation, slope, aspect and landform type data for the Ludian earthquake-stricken area in Yunnan Province. (1) The 1:4,000,000 scale geomorphological data was derived by tracking, collecting and sorting out the "Atlas of Geomorphology of China (1:4,000,000)" edited by Li Bingyuan. The geomorphological map was scanned and registered, then vector digitized with the support of ArcGIS. (2) The DEM dataset was obtained by mosaicking, projection transformation and clipping of SRTM data. The slope and aspect data were calculated using the ArcGIS Spatial Analyst module based on this DEM dataset.
