stream order stuck on 8%

[Marc-OlivierDubois-Chevalier]

Hi, im currently modeling a part of a bassin, to do so i need to run the stream order tool but unfortunately it is stuck on 8%. It has never happened until now. Any ideas on how to fix the issue?

in the Environments section for the tool, there is a big list of the things that could affect the processing, so perhaps you could elaborate on a few things, like whether there is any coordinate conversions going on, the cell size, the extent of the input data , etc

[Marc-OlivierDubois-Chevalier]

Sure thing, i haven't done a coordinate transformation, i use the default cell size of 'Maximum as input' which is 1. Also, i use the extent of my input stream raster and i have checked the pyramide option (with 'neaerest' as resampling option). Should i aggregate the raster to a lower resolution? Finaly, it is stuck on 'updating stream order'

Well, if it is a big raster and highly braided it may take a long time. 

An cell size is 1 meter I presume, which means your inputs and outputs are in the same projected coordinate system (?)  If not, then a lot of work has to be done.

Work locally with locally stored data is the number 1 rule.
