Streams

This layer is an approximate delineation of stream centerlines for visualization purposes only. This layer originates from our Stream Segments layer. it was dissolved by the mhfd_code_stream field. This unique code was accomplished by dropping the segment number from the MHFD Code. This unique code along with the stream name was used for dissolving the streams into stream reaches. Update Frequency: Quarterly Last Updated: March 2026 For questions about this layer, please reach out to [e-mail]本图层仅用于可视化展示，为河道中心线的近似描绘成果。本图层源自我们的河道分段图层（Stream Segments layer），通过mhfd_code_stream字段完成要素融合聚合。该唯一编码通过移除MHFD编码（MHFD Code）中的分段编号生成，结合河道名称被用于将河道整合为河道河段。更新频率：每季度一次；最后更新时间：2026年3月。若对本图层有任何疑问，请联系邮箱[e-mail]。
