GlobeLand30,即“全球30米地表覆盖数据”。地表覆盖是我们在观察、研究赖以生存的地球时,所看到的最直观的映像(景观)。这样的映像包括了自然景观和人文景观,既受到气候、地形和水文的影响,同时也反映了人类活动的方式、强度等,具有自然和人文的综合属性,也可以作为地理教学的素材,并通过与其他要素相互关系的分析,增强对人地关系的理解。该数据涵盖全球陆域范围,包括经过判译的十大类地表覆盖,有两个时相(2000年和2010年),分辨率高达30米。
GlobeLand30, or “Global 30m Surface Coverage Data”. Surface coverage is the most intuitive image (landscape) that we see when we look at the Earth upon which we live. Such images include both natural landscapes and cultural landscapes. They are influenced not only by climate, terrain and hydrology, but also by the way and intensity of human activities, as well as natural and cultural attributes as well as materials for geography teaching. Through the interrelationships with other elements of analysis, to enhance understanding of human relations. The data covers the global land area, including the ten categories of surface coverings that have been interpreted, with two phases (2000 and 2010) and a resolution of up to 30 meters.
