Reconcile Catchment Divides

Description

Reconciles catchment divides according to the output of reconcile_collapsed_flowlines and refactor_nhdplus

Usage

reconcile_catchment_divides(
  catchment,
  fline_ref,
  fline_rec,
  fdr = NULL,
  fac = NULL,
  para = 2,
  cache = NULL,
  min_area_m = 800,
  snap_distance_m = 100,
  simplify_tolerance_m = 40,
  vector_crs = 5070,
  fix_catchments = TRUE,
  keep = 0.9
)

Arguments

catchment	sf data.frame NHDPlus Catchment or CatchmentSP layers for included COMIDs
fline_ref	sf data.frame flowlines as returned by refactor_nhdplus and reconcile_collapsed_flowlines
fline_rec	sf data.frame flowpaths as returned by reconcile_collapsed_flowlines
fdr	character path to D8 flow direction
fac	character path to flow accumulation
para	integer numer of cores to use for parallel execution
cache	path .rda to cache incremental outputs
min_area_m	minimum area in m^2 to filter out slivers (caution, use with care!!)
snap_distance_m	distance in meters to snap SpatRaster generated geometry to polygon geometry
simplify_tolerance_m	dTolerance in meters for simplification of grid-cell based polygons
vector_crs	integer or object compatible with sf::st_crs coordinate reference. Should be a projection that supports area-calculations.
fix_catchments	logical. should catchment geometries be rectified?
keep	Only applicable if fix_catchments = TRUE. Defines the proportion of points to retain in geometry simplification (0-1; default 0.05). See ms_simplify. Set to NULL to skip simplification.

Details

Note that all inputs must be passed in the same projection.

Value

Catchment divides that have been split and collapsed according to input flowpaths
