BigFoot Land Cover Surfaces for North and South American Sites, 2000-2003

The BigFoot project gathered data for nine EOS Land Validation Sites located from Alaska to Brazil from 2000 to 2003. Each site is representative of one or two distinct biomes, including the Arctic tundra; boreal evergreen needleleaf forest; temperate cropland, grassland, evergreen needleleaf forest, and deciduous broadleaf forest; desert grassland and shrubland; and tropical evergreen broadleaf forest. These surfaces were produced from Landsat ETM+ imagery to explicitly characterize the land cover at the BigFoot Sites to provide validation of the MODIS land cover product. BigFoot was funded by NASA's Terrestrial Ecology Program.

BigFoot项目收集了自2000年至2003年分布于阿拉斯加至巴西之间的九个EOS陆地验证站点的数据。每个站点均代表一种或两种独特的生物群落，包括北极苔原、针叶林、温带农田、草地、针叶林、落叶阔叶林；沙漠草地和灌木丛，以及热带常绿阔叶林。这些地表信息由Landsat ETM+影像生成，旨在明确表征BigFoot站点的土地覆盖情况，以对MODIS土地覆盖产品进行验证。BigFoot项目由美国国家航空航天局的地表生态学计划资助。
