Linking remote-sensing estimates of land cover and census statistics on land use to produce maps of land use of the conterminous United States [PDF]

, 2001
Human use of the land has a large effect on the structure of terrestrial ecosystems and the dynamics of biogeochemical cycles. For this reason, terrestrial ecosystem and biogeochemistry models require moderate resolution (e.g., ≤0.5°) information on land
