Streams

---

The stream network data set is derived by thresholding the flow accumulation data set at 1000 km². The resulting raster data set is then processed to identify the stream links and each stream link tagged with its flow accumulation value. Additional attributes on the vectors describe the morphology of the stream network. Descriptions of the vector attributes can be found in the Readme file. This vector data set is available in ARC/INFO export format and in shapefile format.
