v1.3

• Upgraded Python libraries

1.2

• Updated code so it can handle input shapefiles with missing .prj files -- the latest version of MERIT-Basins 'bugfix' does not include them.
• Added ability to save GeoDataFrames as Python pickle files. This should speed up one of the slow steps -- reading shapefiles and constructing the spatial index. This is useful if you use the script more than once.
• Added checks for the presence of the various directories to write output files, and creates them if they are not there.
• Considered upgrading various Python libraries (namely pysheds and shapely), but it looks to be a major effort.

delineator v1.1

Version 1.1 fixes a bug that occurred rarely where the script created a shapely MultiPolygon instead of the expected Polygon.

delineator v1.0

Python scripts for fast, accurate watershed delineation using a hybrid of vector- and raster-based methods.
