Apply the DESPLIM algorithm to a set of input polygons and lines.

Usage

desplim_split_merge(
  input_polygon,
  input_lines,
  input_buildings = NULL,
  line_type_identifier = NULL,
  line_type_hierarchy = NULL,
  parallel = FALSE,
  ...
)

Arguments

input_polygon: object of class sf of type POLYGON to be merged.
input_lines: object of class sf of type LINESTRING or MULTILINESTRING to be used for splitting.
input_buildings: object of class sf of type POLYGON or MULTIPOLYGON. An optional sf object representing buildings which should be considered when splitting and merging. Default is NULL.
line_type_identifier: string; the name of the column in input_lines which contains the line type. Default is NULL.
line_type_hierarchy: list; hierarchical structure of line types used for splitting. Default is NULL. All types can be accessed with "all".
parallel: logical; whether to run the split and merging steps in parallel. If TRUE, uses the future package, where the number of workers should be set using the plan argument. Default is FALSE.
...: additional arguments passed to desplim_split, desplim_merge and desplim_connect_border.

Value

An sf object of POLYGONs resulting from the merge.

Details

The function applies the DESPLIM algorithm to a set of input polygons and lines. The splitting and merging steps are performed in line with the desplim_split and desplim_merge functions for each iteration as defined by line_type_hierarchy.
