资源简介：
BigFoot is designed to provide the spatial context of flux towers
using a combination of in situ ecological data, Landsat ETM+ data, and
ecosystem models. Moreover, BigFoot maps land cover, LAI, fraction
absorbed photosynthetic active radiation, and NPP over a 5 x 5 km area
around an eddy flux tower at ETM+ resolution. They fully characterize
25 MODIS cells around a given tower site, and are able to test a
number of scaling factors that should reveal possible causes of MODIS
mapping errors (thereby providing feedback to algorithm
developers). Finally, BigFoot takes important steps to enhance the
goals of GTOS.
There are nine BigFoot study sites that span eight major biomes, from
desert to tundra, to tropical forest. The BigFoot project collects
data and generates products at several scales of measurement. Selected
results are presented visually in map and graphic galleries organized
by study site.
