Freshwater Rivers and Streams (1:5,000)

This hosted feature layer has been published in RI State Plane Feet NAD 83. These data intended for use in inventory and mapping of fresh water bodies. Limitations due to scale, accuracy and completeness of source material should be kept in mind when using these data. Strahler Stream Ordering was added in December, 2006. Stream ordering is used in watershed analyses and for cartographic purposes.本托管要素图层采用RI州平面英尺（NAD 83）坐标系发布。本数据集适用于淡水水体的清查与制图工作。使用本数据集时，应充分考虑源数据在比例尺、精度与完整性层面的局限性。斯特拉勒河流分级法（Strahler Stream Ordering）于2006年12月被添加至本数据集。该分级方法可用于流域分析及制图相关场景。
