中文摘要 |
土地覆盖是指地球表面当前所具有的自然和人为影响所形成的覆盖物,是地球表面的自然状态,如森林、草场、农田、土壤、冰川、湖泊、沼泽湿地及道路等。土地覆盖(Land Cover)数据集,源数据来自MODIS产品,经过数据格式转换、投影、重采样等预处理。现有格式为TIFF格式,投影为Krasovsky_1940_Albers投影。数据空间分辨率为1000米,时间上,从2001至2020年,每年提供一幅图像。土地覆盖产品的分类采用国际地圈生物圈计划(IGBP, International Geosphere Biosphere Programme)定义的17类,包括11类自然植被分类,3类土地利用和土地镶嵌,3类无植生土地分类。 |
英文摘要 |
Land cover refers to the mulch formed by the current natural and human influences on the earth's surface. It is the natural state of the earth's surface, such as forests, grasslands, farmland, soil, glaciers, lakes, swamps and wetlands, and roads. The Land Cover (LC) dataset is original from MODIS products and preprocessed by format conversion, projection and resampling. The existing format is TIFF and projection is Krasovsky_1940_Albers. The data set has a spatial resolution of 1000 meters and provides one image per year during the period from 2002 to 2020. Land cover products were classified into 17 categories defined by the International Geosphere Biosphere Programme (IGBP), including 11 categories of natural vegetation, 3 categories of land use and Mosaic, and 3 categories of non-planting land. |
