The Landscape Data Commons is an inter-agency monitoring data repository and portal, led by the USDA-ARS at the Jornada Experimental Range, that connects standardized monitoring data to analysis tools to support land management and research. The Landscape Data Commons aggregates and harmonizes core methods data collected across agencies and monitoring programs (e.g., Bureau of Land Management Assessment, Inventory and Monitoring Program, the Natural Resources Conservation Service National Resources Inventory Grazing land On-Site program, the National Wind Erosion Research Network, smaller research and monitoring efforts). With these aggregated data, the Landscape Data Commons supports natural-resource management, modeling, and research.
