Calculate Cross Section Dimensions at Level 1

Calculates level 1 cross section dimensions for the input cross section feature class.

cross_section_dimensions_L1(
  xs_sf,
  lead_n,
  use_smoothing,
  loess_span = 0.5,
  vert_units
)

Arguments

xs_sf

sf object; the full path to a cross section line feature class

lead_n

numeric; The number of features to lead/lag on either side of each feature that will be used to calculate the slope and sinuosity.

use_smoothing

boolean; determines if smoothed elevation values are used to calculate gradient. values are: TRUE, FALSE (default)

loess_span

numeric; the loess regression span parameter, defaults to 0.05

vert_units

character; The DEM vertical units. One of: "m" (meter), "ft" (foot), "us-ft" (us survey foot)

Value

A new cross section data frame with the Level 1 hydraulic geometry dimensions added.
