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.

这个为期两年的项目将建立一个与佐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。该项目将建立在佐治亚大学海洋研究所、佐治亚州雅典遥感和测绘科学中心以及南卡罗来纳大学贝勒·W·巴鲁克海洋生物学和沿海研究所的现有地理信息系统数据库的基础上。萨凡纳州立学院和南卡罗来纳州北湾的巴鲁克研究所的小组也将参与其中。这个项目的目标将有三个方面。1)建立一个与1983年北美基准相联系的多级嵌套数据库，在区域和特定地点尺度上提供沿海土地利用/土地覆盖、水文学和植被的标准化信息类别。2)开发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)确定处理区域和特定地点研究问题所需数据的最佳比例尺和分辨率，包括评估在数据库的区域层和特定地点层之间移动所产生的信息收益或损失。
