Catchment file selection (Question) #5

Closed kokubadejo closed 6 months ago

kokubadejo commented 11 months ago

How different are the standard catchment files to the ones marked 'minor bug fix for coastline pixels'. I tried batch delineating a couple of points using the standard catchment shapefiles, and for a point in basin 78, there seems to be a missing feature / gap in the polygon. I noticed that this is not the case in the bug-fixed file and was wondering which one was better to use in general

I have not done a detailed comparison of the dataset versions. My understanding is that the "bug fix" version had only very minor changes.

Ahh okay, I guess the results shouldn't be significantly different then. Thanks!

kokubadejo commented 11 months ago

Also, are there any other files that have updates, or bug fixes?

None that I am aware of. If HydroSHEDS v2 ever comes out, I will consider integrating that.
