Cannot replicate the example using 'elevation.tiff'

[johnratcliff]

I am just getting started with pysheds and I am trying to replicate the example that is posted, but I get different results for the flow direction, accumulation, catchment delineation and river network extraction. I have essentially copied and pasted the script into my own Jupyter notebook, so I am confused as to why. I have attached images of the results that I get. The code is the same as the example code on the ReadMe page. If someone can help me out, I would be greatly appreciative.

Looks like you forgot to fill pits and depressions and resolve flats. If I leave them out I get the same picture as you.

# Condition DEM
# ----------------------
# Fill pits in DEM
pit_filled_dem = grid.fill_pits(dem)

# Fill depressions in DEM
flooded_dem = grid.fill_depressions(pit_filled_dem)
    
# Resolve flats in DEM
inflated_dem = grid.resolve_flats(flooded_dem)

Thanks @philippkraft!

Okay, thanks! Sounds like that's probably it so I'll give it another try. John
