New#
Restore FlwdirRaster.inflow_idxs and FlwdirRaster.outflow_idxs methods
0.5 (28-Sept-2021)#
New#
General Flwdir object for 1D vector based (instead of raster based) flow directions
flwdir.from_dataframe methods to derive a Flwdir object from a (Geo)DataFrame based on the row index and a column with downstream row indices.
dem.fill_depressions and pyflwdir.from_dem methods to derive flow directions from DEMs based on Wang & Lui (2015)
gis_utils.get_edge method to get a boolean mask of valid cells at the interface with nodata cells or the array edge.
gis_utils.spread2d method to spread valid values on a 2D raster with optional friction and mask rasters
FlwdirRaster.dem_dig_d4 method to adjust a DEM such that each cell has a 4D neighbor with equal or lower elevation.
FlwdirRaster.fillnodata method fill nodata gaps by propagating valid values up or downstream.
region.region_outlets method; which is also wrapped in the new FlwdirRaster.basin_outlets method
region.region_dissolve method to dissovle regions into their nearest neighboring region
FlwdirRaster.subbasins_areas method to derive subbasins based on a minimal area threshold
Improved#
added type=”classis” for bottum-up stream order to FlwdirRaster.stream_order, default is type=”strahler”
return subbasin outlet indices for all FlwdirRaster.subbasin* methods
improved subgrid slope method with optional lstsq regression based slope
FlwdirRaster.streams takes an optional idxs_out argument to derive stream vectors for unit catchments
FlwdirRaster.streams takes an optional max_len argument to split large segments into multiple smaller ones.
Using the new Flwdir object as common base of FlwdirRaster to share methods and properties
gis_utils.IDENTITY transform has North -> South orientation (yres < 0) instead of S->N orientation which is in line with flow direction rasters.
new restrict_strord argument in FlwdirRaster.moving_average and FlwdirRaster.moving_median methods to restrict the moving window to cells with same or larger stream order.
Bugfix#
strahler stream_order method gave incorrect results
basins.subbasins_pfafstetter reimplementation to fix mall functioning when jitted
FlwdirRaster.streams fix when called with optional min_sto argument
Deprecated#
FlwdirRaster.main_tributaries method is deprecated due to mallfunctioning when jitted
