Row bind coverage for a feature based on a coverage feature

Usage

bind_sf_coverage(
  x,
  coverage,
  coverage_nm = NULL,
  .id = "name",
  x_arg = caller_arg(x),
  coverage_arg = caller_arg(coverage),
  id_arg = caller_arg(.id),
  combine = FALSE,
  error_call = caller_env()
)

st_make_valid_coverage(
  x,
  y,
  combine = FALSE,
  is_coverage = TRUE,
  .fn = sf::st_difference
)

st_make_valid_union(x, combine = FALSE, is_coverage = TRUE)

Arguments

x

A input sf object

coverage

A sf, sfc, or bbox object that covers x.

coverage_nm

Name to use for coverage feature assigned as value for .id column, Default: NULL

.id

.id column name, must be present in x Default: 'name'

x_arg, coverage_arg, id_arg

Argument names for error messages if bind_sf_coverage() is used as a wrapper function.

combine

If TRUE, use sf::st_combine() before passing x to sf::st_union()

error_call

The execution environment of a currently running function, e.g. caller_env(). The function will be mentioned in error messages as the source of the error. See the call argument of abort() for more information.

y

Second parameter for st_make_valid_coverage()

is_coverage

logical; if TRUE, use an optimized algorithm for features that form a polygonal coverage (have no overlaps)

.fn

Defaults to sf::st_difference

Value

A sf object or a sfc object

Details

bind_sf_coverage() and the related helper functions st_make_valid_coverage() and st_make_valid_union() take a sf object and create a non-intersecting coverage area of a surrounding geography defined by a second sf, sfc, or bbox object. This was originally developed for the make_area_xwalk() function in the getACS package.
