st_edge_length: Calculate edge length between two geometries

In raff-k/VLSM: Vector-based Landscape Metrics

Calculate edge length between two geometries

Description

This function calculates the edge length between two geometries.

Usage

st_edge_length(
  x,
  y,
  dist.x = 0,
  dist.y = 0,
  geom.boundary = NULL,
  do.preProcessing = TRUE,
  return.geom = FALSE,
  quiet = TRUE
)

Arguments

x	polygon of class sf representing the basis geometry
y	polygon of class sf representing geometry of which the edge length is calculated
dist.x	buffer distance in mapping units around geometry using sf::st_buffer. Default: 0
dist.y	buffer distance in mapping units around geometry using sf::st_buffer. Default: 0
geom.boundary	polygon of class sf representing subregions, e.g. administrative boundaries
do.preProcessing	If TRUE (default), the input of geom.frag is, first, dissolved to single part feature, and second, splitted to multi-parts
return.geom	If set to TRUE, intermediate geometries are returned as well. Default: FALSE
quiet	If set to FALSE, actual state is printed to console. Default: TRUE.

Value

list with edge length, and if return.geom is TRUE also the edge-length-geometry (and eventually buffer results).

Note

If the edge line has incomprehensible gabs(can happen for "complicated" geometries), it can help to use a small buffer distance (< 1, e.g. 1e-04) to get a complete edge line.
