资源简介：
数据包含东北地区地震灾区高程、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 encompasses elevation, slope aspect, geomorphic type data and other relevant geospatial data for the earthquake-hit regions in Northeast China.
(1) The 1:4,000,000-scale geomorphic data was traced, collected and compiled based on the *1:4,000,000 Geomorphic Map of China* edited by Li Bingyuan, and was derived through scanning, geometric registration and vectorization of the scanned geomorphic map with the support of ArcGIS.
(2) The DEM dataset was generated from SRTM data via mosaicking, projection transformation and clipping. The slope and aspect data were calculated using the ArcGIS Spatial Analysis Toolbox based on the obtained DEM dataset.
