中国GlobeLand30地表覆盖数据集 (2000年、2010年、2020年)
收藏资源简介:
数据集通过网络挖掘获取,数据集包含我国及周边区域的地表覆盖类型数据,数据包括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。原始数据名称为GlobeLand30,是中国研制的30米空间分辨率全球地表覆盖数据,目前有2000年、2010年和2020年三个版本。数据采用WGS-84坐标系,按照不同的纬度区域,采用不同的分幅方式存储。这些数据经过预处理、分类、后处理和精度评估等步骤,最终生成30米分辨率土地覆盖数据。
This dataset is collected via web data mining, and contains land cover type data for China and its adjacent regions. It includes 10 first-level land cover categories, namely cropland, forest land, grassland, shrubland, wetland, water bodies, tundra, artificial surfaces, barren land, glaciers and permanent snow cover. The original dataset, named GlobeLand30, is a 30-meter spatial resolution global land cover product developed by China, with three official versions released in 2000, 2010 and 2020 respectively. The data adopts the WGS-84 coordinate system and is stored using different tiling schemes based on different latitude zones. After undergoing preprocessing, classification, post-processing and accuracy assessment, these data are finally processed into 30-meter resolution land cover datasets.
