Template:Streams from Raster

Streams from Raster

The tool converts a raster stream file into a vector file, where streams are represented as polylines. It requires specifying the raster streams file, the D8 flow pointer file, and the output vector file. The vector output includes fields for stream values and the length of each stream segment.

Input parameters

• Input raster streams file – The input raster streams file is a grid-based dataset where cells represent stream locations, typically derived from flow accumulation data.
• Input raster D8 pointer file – This file is required to define the flow paths in the stream network for conversion into vector format.

Output parameters

• Output coverage name – Enter the name for the new coverage.
• D8 pointer uses the ESRI style scheme – Optional flag that indicates whether the input D8 pointer file follows the ESRI convention for flow direction encoding.
• Do you want to preserve all vertices in output (i.e. no straight-line generalization) – Optional flag that, ensures all vertices from the input raster are included in the output vector file, preventing straight-line generalization and maintaining the full detail of the stream paths.
