DEPRECATED: Add NHDPlus Network Attributes to a provided network.

Description

Given a river network with required base attributes, adds the NHDPlus network attributes: hydrosequence, levelpath, terminalpath, pathlength, down levelpath, down hydroseq, total drainage area, and terminalflag. The function implements two parallelization schemes for small and large basins respectively. If a number of cores is specified, parallel execution will be used.

Usage

add_plus_network_attributes(
  net,
  override = 5,
  cores = NULL,
  split_temp = NULL,
  status = TRUE
)

Arguments

net	data.frame containing comid, tocomid, nameID, lengthkm, and areasqkm. Additional attributes will be passed through unchanged. tocomid == 0 is the convention used for outlets. If a "weight" column is provided, it will be used in get_levelpaths otherwise, arbolate sum is calculated for the network and used as the weight.
override	numeric factor to be passed to get_levelpaths
cores	integer number of processes to spawn if run in parallel.
split_temp	character path to optional temporary copy of the network split into independent sub-networks. If it exists, it will be read from disk rather than recreated.
status	logical should progress be printed?

Value

data.frame with added attributes
