中国1：100万数字地貌数据（F-47 曼德勒）

中国数字地貌数据库包括三个层次的数据：（1）中国1:400万形态地貌图（李炳元，1994）和中国1:400万构造地貌图（陈志明，1994）数字栅格图（原始纸质图扫描）、矢量数据（albers投影）、数据说明文档，总数量量达2G。（2）中国1:100万15幅老地貌图（20世纪80年代）的数字栅格图（原始纸质图扫描）、矢量数据（ThansverseMercator投影）和数据说明文档，总数据量达2G。（3）基于遥感影像、地质图、基础地理底图、老地貌图、SRTM-DEM等多源数据解译、更新、集成的全国64幅陆地无缝拼接的地貌数据，以100万标准分幅方式存储，ThansverseMercator投影，数据量达2G以上。以及中国1:100万数字地貌分类体系及中国数字地貌遥感解译技术规程等说明文档。

The China Digital Geomorphology Database includes three tiers of data: 1. Digital raster maps (scanned from original paper maps), vector data (Albers projection), and data documentation for the 1:4,000,000 Chinese morphologic geomorphology map (Li Bingyuan, 1994) and 1:4,000,000 Chinese tectonic geomorphology map (Chen Zhiming, 1994), with a total data volume of 2 gigabytes. 2. Digital raster maps (scanned from original paper maps), vector data (Transverse Mercator projection), and data documentation for 15 pieces of 1:1,000,000 vintage geomorphology maps (from the 1980s) across China, with a total data volume of 2 gigabytes. 3. Nationwide 64-sheet land seamless mosaic geomorphology data interpreted, updated and integrated from multi-source data including remote sensing imagery, geological maps, basic geographic base maps, vintage geomorphology maps and SRTM-DEM. The data is stored in the 1:1,000,000 standard sheet division format with Transverse Mercator projection, with a total data volume of over 2 gigabytes. Additionally, supporting documentation such as the China 1:1,000,000 Digital Geomorphology Classification System and the Technical Regulations for Remote Sensing Interpretation of China Digital Geomorphology are also provided.
