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

这一为期两年的项目将建立一个区域数据库， 位于格鲁吉亚和南卡罗来纳州边界的盐沼生态系统。 的 该项目将建立在现有地理信息系统的基础上 数据库在格鲁吉亚大学海洋研究所， 佐治亚州雅典遥感和制图科学中心， 南卡罗来纳州大学贝儿W。巴鲁克研究所 海洋生物学和海岸研究。 萨凡纳州立大学 学院和巴鲁克研究所在北入口，SC，也将是 涉案 该项目的目标有三个方面。 1)建设 一个多级嵌套数据库， 1983年，沿海土地信息标准化分类 区域和地点的土地利用/土地覆被、水文和植被- 具体尺度。 2)数据集成和 适用于施工的分析技术， 使用沿海地区多级嵌套数据库。 第三章 确定数据的最佳尺度和分辨率 需要解决区域和特定地点的问题 研究，包括评估信息的获得或损失 由于在区域层和特定场地层之间移动， 的数据库。

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.
