全球板块地貌单元数据集

该数据为全球板块地貌单元数据集，包含全球地质构造数据（Global Geological Provinces and Tectonic Plates，2022发布）和全球基本地貌类型单元数据集(2023年)。全球地质构造数据包含了各个板块的多边形数据，包含了板块名称、板块代码、板块类型等属性信息，数据为矢量格式；全球基本地貌类型单元数据包含两级地貌类型单元，第一级地貌单元为平原，丘陵，小起伏山地，中起伏山地，大起伏山地和极大起伏山地六类，第二级地貌类型依据海拔高度将平原，丘陵和山地等一级地貌单元进一步细分为不同海拔高程级别的类型，共23类。数据为栅格版本数据，分辨率为30m。

This is a global plate geomorphic unit dataset, which includes two parts: the Global Geological Provinces and Tectonic Plates (released in 2022) and the global basic geomorphic type unit dataset (released in 2023). The Global Geological Provinces and Tectonic Plates contains polygon data of each tectonic plate, with attribute information such as plate name, plate code, plate type and other related attributes, and the data is in vector format. The global basic geomorphic type unit dataset has two levels of geomorphic units: the first-level geomorphic units consist of six categories, namely plain, hill, low-relief mountain, medium-relief mountain, large-relief mountain and extremely large-relief mountain. The second-level geomorphic types further subdivide the first-level geomorphic units such as plains, hills and mountains into 23 types at different elevation levels based on altitude. The data is raster data with a spatial resolution of 30 meters.
