中国1：100万数字地貌数据（K-46 哈密）
收藏资源简介：
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 consists of three tiers of data: (1) Digital raster maps (scanned from original paper prints), vector data (Albers projection), and data documentation for the 1:4,000,000-scale morphologic geomorphology map of China (Li Bingyuan, 1994) and the 1:4,000,000-scale tectonic geomorphology map of China (Chen Zhiming, 1994), with a total data volume of 2 GB. (2) Digital raster maps (scanned from original paper prints), vector data (Transverse Mercator projection), and data documentation for 15 vintage 1:1,000,000-scale geomorphology maps from the 1980s, with a total data volume of 2 GB. (3) 64-piece nationwide land seamless mosaic geomorphology data interpreted, updated and integrated from multi-source data including remote sensing imagery, geological maps, basic geographic base maps, old geomorphology maps, SRTM-DEM and other relevant sources. This dataset is stored in 1:1,000,000 standard map sheets with Transverse Mercator projection, with a total data volume exceeding 2 GB. In addition, supporting documentation such as the 1:1,000,000-scale China Digital Geomorphology Classification System and the Technical Regulations for Remote Sensing Interpretation of China Digital Geomorphology are also included in the database.
