Simplify MULTIPOLYGON to POLYGON geometry in an sf class object

Function to simplify MULTIPOLYGON geometry to POLYGON geometry in an sf class object by selecting the largest segment of the MULTIPOLYGON

Usage

simplify_multipolygon_crowns(trees_poly)

Arguments

trees_poly

data.frame. A data frame of sf class with POLYGON,MULTIPOLYGON geometry (see sf::st_geometry_type()) and the column treeID

Value

A sf class object data frame

Examples

 if (FALSE) { # \dontrun{
 f <- paste0(system.file(package = "cloud2trees"),"/extdata/crowns_poly.gpkg")
 crowns <- sf::st_read(f, quiet = T)
 crowns %>% sf::st_geometry_type() %>% table()
 crowns_simp <- simplify_multipolygon_crowns(crowns)
 crowns_simp %>% sf::st_geometry_type() %>% table()
 } # }
