I have a shapefile which contains the streams that were digitized from a satellite Image. I would like to calculate the stream order for this data. The data does not exactly match the DEM that I have, since the satellite image was of much higher resolution.
Is there any arcscript, code or readymade tool which I could use to calculate the stream orders?
I have Arcgis 10 with spatial & 3D analyst, as well as QGIS.
Answer
Check out the NVS Vector Stream Tool which ...
is a user-friendly ArcCatalog (9.3.x) Toolbox geoprocessing tool which simply assigns a numeric order to segments of a poly line feature class. Unlike the Spatial Analyst Tools for Hydrography, this tool solely uses vector stream data instead of raster stream data accompanied by a flow direction raster.
...
NVS Vector Stream Tool installers are available for both ArcGIS Desktop 10.0 and ArcGIS Desktop 9.3.1.
