Major Rivers Areas Dataset

Overview This Feature Service provides spatial data on major river areas within a defined geographic region in the southeastern United States. It includes detailed polygon features representing significant river basins and water bodies. Feature Layer Major Rivers Areas: This layer delineates major river polygons with associated hydrological attributes such as the base major identifier, perimeter length, and shape area and length metrics. The attributes also contain descriptive names and types of the rivers, enabling identification and categorization. Geographic Coverage The dataset covers an area spanning parts of southeastern US states, roughly bounded by coordinates extending from the Gulf Coast near Alabama and Florida to inland areas eastward. This coverage supports regional hydrologic and environmental analyses within this area. Use Cases Hydrological modeling and watershed analysis. Environmental resource management and conservation planning. Infrastructure planning related to water resources. Educational and research purposes focusing on river systems and aquatic habitats.概览 本要素服务提供美国东南部指定地理区域内主要河流区域的空间数据，包含代表重要流域与水体的精细面状要素。 要素图层：主要河流区域 该图层勾勒出主要河流面状要素，并附带相关水文属性，包括基础主标识符、周长长度、形状面积与长度度量值。属性信息中还包含河流的名称与类型描述，便于识别与分类。 地理覆盖范围 本数据集覆盖美国东南部部分州域，大致坐标范围为从阿拉巴马州与佛罗里达州附近的墨西哥湾沿岸向东延伸至内陆区域，可支撑该区域内的水文与环境分析工作。 应用场景 水文建模与流域分析；环境资源管理与保护规划；水资源相关基础设施规划；针对河流系统与水生栖息地的教育与研究用途。
