Generate Cross Sections Across Hydrographic Network

Usage

cut_cross_sections(
  net,
  id = NULL,
  cs_widths = 100,
  num = 10,
  smooth = TRUE,
  densify = 2,
  rm_self_intersect = TRUE,
  fix_braids = FALSE,
  terminal_id = NULL,
  braid_threshold = NULL,
  version = 2,
  braid_method = "comid",
  precision = 1,
  add = FALSE
)

Arguments

net: Hydrographic LINESTRING Network
id: Unique Identifier in net
cs_widths: Bankfull Widths (length of cross sections for each net element)
num: Number of transects per Net element
smooth: logical, whether to smooth linestring geometries or not. Default is TRUE.
densify: numeric, how many times more points should be added to linestrings. Default is 2.
rm_self_intersect: logical, whether to remove self intersecting transect linestrings
fix_braids: logical, whether to fix braided transect lines or not. If TRUE, linestrings that are part of a braided network are augmented. Default is FALSE.
terminal_id: character, column name containing a unique identifier, delineating separate networks in the 'net' dataset. Default is NULL which will best effort determine the connected components in the network to try and create a 'component_id' column in 'net'
braid_threshold: numeric value, value of the total length of all flowlines in a braid. Only braids with total flowline lengths less than or equal to the threshold will be considered by function (i.e. determines that maximum braid size that fix_braid_transects() should operate on). Default is NULL, which will attempt to fix all the braid transects in the data
version: integer, version number of braid algorithm to use, either 1 or 2. Default is 2.
braid_method: The method to determine the geometries to cut. Options are "comid", "component", or "neighbor". Default is "comid"
precision: int, distance in meters. Only applicable when fix_braids = TRUE. This is the number of meters to approximate final cross section linestring length. Increasing this value will decrease runtime of cross section extension algorithm. Value you must be greater than 0. Default is 1
add: logical indicating whether to add original 'net' data to the outputted transect lines. Default is FALSE.
