Global landform and lithology class at 250 m based on the USGS global ecosystem map

Layers include: lithology (15) and landform (7) indicator maps (0-100%). Derived from the USGS Global Ecosystem Map, i.e. the EcoTapestry map. Water bodies masked out. Antarctica is not included. To access and visualize maps use: OpenLandMap.org If you discover a bug, artifact or inconsistency in the maps, or if you have a question please use some of the following channels: Technical issues and questions about the code: https://gitlab.com/openlandmap/global-layers/issues General questions and comments: https://disqus.com/home/forums/landgis/ All files internally compressed using "COMPRESS=DEFLATE" creation option in GDAL. File naming convention: dtm = theme: digital terrain models / relief and soil, lithology = variable: lithological class, usgs.ecotapestry = determination method: USGS Global Ecosystem Map, p = probability 0-100%, 250m = spatial resolution / block support: 1 km, s0..0cm = vertical reference: land surface, 2014 = time reference: year 2014, v1.0 = version number: 1.0,本数据集包含两类图层：岩性（lithology）（共15类）与地貌（landform）（共7类）指标图，值域范围为0-100%。本数据集衍生自美国地质调查局（United States Geological Survey, USGS）全球生态系统地图（即EcoTapestry地图）。已对水体进行掩膜剔除，且未纳入南极洲区域。如需访问并可视化相关地图，请访问OpenLandMap.org。 若您发现地图存在错误、伪影或不一致问题，或有任何咨询需求，请通过以下渠道反馈： - 代码相关技术问题与咨询：https://gitlab.com/openlandmap/global-layers/issues - 通用咨询与意见反馈：https://disqus.com/home/forums/landgis/ 所有文件内部均采用地理数据抽象库（Geospatial Data Abstraction Library, GDAL）的"COMPRESS=DEFLATE"创建参数进行压缩。文件命名规范如下： dtm = 主题：数字地形模型/地形与土壤； lithology = 变量：岩性类别； usgs.ecotapestry = 生成方法：美国地质调查局全球生态系统地图； p = 概率（值域0-100%）； 250m = 空间分辨率/区块支撑尺度：1千米； s0..0cm = 垂直基准：地表； 2014 = 时间基准：2014年； v1.0 = 版本号：1.0。
