Join Stream Segments

fwa_join_stream_segments.Rd

Converts a tibble of stream segment linestrings to stream linestrings.

Usage

fwa_join_stream_segments(
  x,
  elevation = FALSE,
  reverse = integer(),
  source = NULL,
  zoom = 12
)

Arguments

x

An sf tibble with a column blk and linestrings of stream segments.

elevation

A flag specifying whether to use the elevation to determine stream direction (or use the direction of the provided linestrings)

reverse

A whole numeric vector of streams to reverse direction ignoring elevation.

source

A string of the source of the elevations if elevation = TRUE. Possible values are "elevatr" (no API key required) and "google" (requires a Google Maps Elevation API key). If NULL (the default) and elevation = TRUE "google" is used but this is [Deprecated] and source should be set explicitly.

zoom

A whole number between 1 and 14 of the zoom level of the Terrain Tiles. Higher zoom levels have a finer resolution but take longer to download. Ignored if elevation = FALSE or source = "google".

Value

An sf tibble with the columns blk and sfc column point geometry.

network <- fwa_add_collection_to_polygon(watershed)
network <- select(network, blk = blue_line_key)
fwa_join_stream_segments(network)
