Alternative futures: These are scenario-based assessments of possible future conditions conducted by a collaboration among landscape planners and academic and government scientists. A summary of some projects is in a downloadable document [PDF 973KB] taken from a poster presented at an US Environmental Protection Agency Science Forum. More details about some projects are contained at their websites or in publications.
Biodiversity: These are projects conducted by a collaboration among government scientists from several agencies in the US and Canada, and academic scientists.
Global Grids: Discrete global grids were investigated by the US Environmental Protection Agency, the US Forest Service, the Geography Faculty at Oregon State University, and collaborators from 1989 through 2008. This work was initiated by the US Environmental Protection Agency as part of the development of their Environmental Monitoring and Assessment Program. Accumulated references: References to articles, reports and websites on global grids, spherical tessellations, planar tessellations, and methods for computing on these surfaces.
Energy Systems Analysis: The EMERGY concept of evaluating all goods and services has been developed by Howard T. Odum and his students and colleagues over many decades. An introductory lecture explains the basic concepts of energy systems analysis and emergy with applications to the comparing well-being of nations.
Freshwater fish assemblages: This work was initiated by the US Environmental Protection Agency to develop a dynamic, spatially-explicit simulation model for species pools in stream networks. A page size version of a poster presented at the 2005 Oregon Chapter of the American Fisheries Society annual meeting is available. [PDF]
Ecological Regions: The US Environmental Protection Agency Corvallis Oregon Laboratory conducted a research program for many years in the development of ecological regions to aid in environmental management. This work covered the 48 contiguous United States plus Alaska and had two major levels of resolution. In addition The US EPA collaborated with agencies in the Canadian and Mexican governments to create two additional levels covering North America. From the coarsest to the finest resolutions the North American levels are labeled I and II, and the levels for just the contiguous 48 states are labeled III and IV. The work in developing levels III and IV for Minnesota is one example. For more information and links to the full body of work.
Computer Graphics and Spatial Analysis: This is a sample of research from the 1970s and 1980s at the Laboratory for Computer Graphics and Spatial Analysis at the Harvard University Graduate School of Design.
