Cannot find pour point for high resolution data #147

Closed lar84 closed 3 years ago

lar84 commented 3 years ago

Hello,

Does anyone have suggestions for identifying the pour point when the raster resolution is finer than bankful width? The resulting catchments are tiny and do not show the full extent of the basin. I'm assuming that the flow accumulation path is only a single pixel wide even though the actual channel is much wider. How do I properly select the pour point to capture/fall along the flow accumulation pathway? Is my only option to keep guessing until I find the right spot or do I have to resample (coarsen) the raster?

Just found the snap_to_mask method, so I'm closing this. Thanks for the awesome library!
