Geographic Database for the Salt Marsh Ecosystem of the Southeastern United States

这个为期两年的项目将建立一个与乔治亚州和南卡罗来纳州接壤的盐沼生态系统的区域数据库。该项目将建立在乔治亚大学海洋研究所、乔治亚州雅典遥感和测绘科学中心以及南卡罗莱纳大学贝尔W.巴鲁克海洋生物学和海岸研究所现有的地理信息系统数据库的基础上。萨凡纳州立大学和南卡罗来纳州北湾巴鲁克研究所的研究小组也将参与其中。这个项目有三个目标。1)建立以1983年北美基准为基础的多层次嵌套数据库，包括沿海土地利用/土地覆盖、水文和植被在区域和特定地点尺度上的标准化分类信息。2)发展适合沿海地区多层次嵌套数据库建设和使用的数据集成和分析技术。3)确定解决区域和特定地点研究问题所需数据的最佳尺度和分辨率，包括评估由于在数据库的区域和特定地点层之间移动而产生的信息的增益或损失。

This two-year project will lead to a regional database for the salt marsh ecosystem bordering Georgia and South Carolina. The project will be built upon existing geographic information system databases at the University of Georgia Marine Institute, the Center for Remote Sensing and Mapping Science in Athens, GA and the University of South Carolina Belle W. Baruch Institute for Marine Biology and Coastal Research. Groups at Savannah State College and the Baruch Institute at North Inlet, SC, will also be involved. The goals of this project will be threefold. 1) Construction of a multi-level nested database tied to the North American Datum of 1983, with standardized classes of information for coastal land use/land cover, hydrology, and vegetation at regional and site- specific scales. 2) Development of data integration and analysis techniques that are appropriate for the construction and use of multi-level nested databases of coastal areas. 3) Determination of the optimum scales and resolutions of data needed to address questions for regional and site-specific studies, including assessments of the gain or loss of information as a result of moving between regional and site-specific layers of the database.
