The USGS Land Use and Climate Change Team has recently created a new website that describes the Land Use and Carbon Scenario Simulator (LUCAS). ST-Sim is used as the core engine in LUCAS for modeling land use and land cover change and for tracking carbon pools and fluxes.  The LUCAS website highlights a number of diverse applications ranging from local scale scenario analyses of management options for the Great Dismal Swamp to national scale land use projections.
