I have a recently-updated extract from NHD High Resolution (updated in last 6 months) which means it hasn't been cranked through NHDPlus, and won't for many years to come, and thus has no Stream Order (Strahler) attribute.
Running it through Arc Hydro (burn streams) and then through SA Stream Order tool doesn't work: That generates a new stream network! Converting the NHD to a raster and combining it with FDR, another miserable fail.
A few tools (RivEX, NVS Vector Stream Tools) "Claim" they have the ability to determine stream order from a vector network, but I have yet to see that work, and their tools are made for "Lab" (perfect) environments.
I'm able to generate FromNODE ToNODE on this network, is there some easy-button in Arc Toolbox that can pull this off? REALLY need to have Stream Order on this dataset covering 700,000 acres, will take the interns a long time......
