net_sample: Create Network Reaches, Points and Transects

In dkopp3/MMASN: Multi-Scale Morphomettic Analysis of Stream Networks

Description

Splits network COMIDs into reaches, identifies midpoints and creates lateral transects

Usage

net_sample(
  network,
  vaa,
  n = 5,
  what = c("reaches", "midpoints", "transects"),
  NHDCatchments = NULL,
  keep.divergent = F
)

Arguments

network	a single network extracted from NHDPlusV2
vaa	NHDPlusV2 value added attributes table, PlusFlowlineVAA.dbf"
n	number of reaches per network COMID
what	one of c("reaches", "midpoints", "transects")
NHDCatchments	NHDPlusV2 catchment coverage, Catchment.shp, required if what = "transects"
keep.divergent	logical keep divergent flow paths

Value

sf object of either lines or points. Transects are perpendicular to the reach
