Convert sf LINESTRING objects to POLYGON objects representing all fundamental cycles within the LINESTRING objects.

Convert sf LINESTRING objects to POLYGON objects representing all fundamental cycles within the LINESTRING objects.

Usage

dodgr_sflines_to_poly(sflines, graph_max_size = 10000, expand = 0.05)

Arguments

sflines

An sf LINESTRING object representing a network.

graph_max_size

Maximum size submitted to the internal C++ routines as a single chunk. Warning: Increasing this may lead to computer meltdown!

expand

For large graphs which must be broken into chunks, this factor determines the relative overlap between chunks to ensure all cycles are captured. (This value should only need to be modified in special cases.)

Value

An sf::sfc collection of POLYGON objects.
