import_rivers

R Documentation

Prepare rivers for connectivity analyses

Description

Reads and prepares geospatial river line data for use in river_net(). Only the largest fully connected component of the network is retained; river lines that are part of disconnected secondary networks are discarded.

Usage

import_rivers(rivers, quiet = FALSE)

Arguments

`rivers`	A character string specifying the path to a shapefile of river lines, or an `sf` object representing river geometries.
`quiet`	Logical. If `FALSE` (default), plots the imported river lines in black over the original lines in red so that removed rivers are highlighted.

Value

An object of class rivers, suitable for use with enforce_dendritic() or as input to river_net().

Examples

rivers_in <- import_rivers(yamaska_rivers)

# This can also be done quietly to omit plotting river lines after importing
rivers_in <- import_rivers(yamaska_rivers, quiet = TRUE)
