Impact/Purpose:
The primary objectives of this research are to:
- Provide information on the variability in water supply that can be expected under varying climatic conditions. Early efforts will be focused on assembling regional databases for at least two counties (Mecklenberg County and York County) within SEQL region that can be used for water supply generation and model development.
- Develop tools that will help improve our ability to evaluate, study, and model linkages between different types of environmental systems: hydrologic, geomorphic, ecological, and climatic.
- Explore the use of annual and seasonal measurements of large lake surface temperatures as a new ecological indicator of the overall thermal content of those lakes, and construct an estimator of seasonal large lake heat budgets.
Description:
The Mid-Atlantic region is comprised of southern New York, southern and western New Jersey, Pennsylvania, West Virginia, Maryland, Virginia, northeastern North Carolina, Delaware, and Washington, DC. It is an ecosystem rich in streams, wetlands, forests, estuaries, breeding birds, biological diversity and a large human population, This collection of digital coverages willprovide researchers with the resources to document the alteration of critical landscape ecological components and processes within the Mid-Atlantic region, Examples are provided which demonstrate the changes In land use and land cover within the region., The researcher will be able to take advantage of the combined resources of 1979 North American Landscape Characterization ,(NALC) imagery processed into land use / land cover and the National Land Cover Data (NLCD) aggregated to the same land rover class. These coverages are available in both 60 and 120 meter resolution,
Early analysis has shown that research preformed using the 120 resolutions coverages tended to minimize collection, sensor difference.
