2020年ESA WorldCover 10米全球土地覆盖数据集

该数据集获取自欧洲航天局。欧洲航天局（ESA）WorldCover 10 m 2020产品根据Sentinel-1和Sentinel-2数据，以10 m分辨率提供2020年全球土地覆盖图。世界覆盖产品有11个土地覆盖类别，与联合国粮农组织的土地覆盖分类系统保持一致，并在欧空局世界覆盖项目的框架内生成。
GlobeLand30采用WGS-84坐标系，共包括10个一级类型，分别是：耕地、林地、草地、灌木地、湿地、水体、苔原、人造地表、裸地、冰川和永久积雪。
GlobeLand30分幅数据由地表覆盖数据文件、坐标信息文件、分类影像接图表文件、元数据文件4部分组成。其中：
1) 地表覆盖数据文件是指存储分幅地表覆盖分类信息的文件；
2) 坐标信息文件是指记录分幅数据坐标信息的文件；
3) 分类影像接图表文件是指记录分类所用的主要影像范围及获取时间的矢量文件；
4) 元数据文件指记录分幅数据元数据信息的文件。"

This dataset is sourced from the European Space Agency (ESA). The ESA WorldCover 10 m 2020 product provides global land cover maps for 2020 at a 10 m resolution, based on Sentinel-1 and Sentinel-2 data. The WorldCover product includes 11 land cover categories, which align with the land cover classification system of the Food and Agriculture Organization of the United Nations (FAO), and was developed under the framework of the ESA WorldCover project.

GlobeLand30 adopts the World Geodetic System 1984 (WGS-84) coordinate system, and contains a total of 10 primary types, namely: cultivated land, forest land, grassland, shrubland, wetland, water body, tundra, artificial surfaces, bare land, glaciers and permanent snow cover.

The tiled data of GlobeLand30 consists of four parts: land cover data file, coordinate information file, classified image mosaic chart file, and metadata file. Specifically:
1) Land cover data file: a file that stores the land cover classification information of the tiled data;
2) Coordinate information file: a file that records the coordinate information of the tiled data;
3) Classified image mosaic chart file: a vector file that records the main image ranges and acquisition times used for classification;
4) Metadata file: a file that records the metadata information of the tiled data.
