Quantify spatial data in vector format

measure_vector_kgc() counts the Köppen-Geiger climate classification in the range cropped with raster_kgc(), and calculates the basic spatial features of a vector geometry such as perimeter and area. quantify_vector_kgc(), in addition, summarizes the counts.

Usage

quantify_vector_kgc(geom, overwrite = FALSE)

measure_vector_kgc(geom, overwrite = FALSE)

Arguments

geom

An sfc or sf object. A path to sf-readable file is accepted.

overwrite

A logical. If TRUE, the cache is not used and overwritten. Relevant only when geom is a path to a file.

Value

quantify_vector_kgc() returns a data.frame.

measure_vector_kgc() returns a list.

Examples

geom = rnaturalearth::ne_countries(country = "Japan") |> sf::st_geometry()
measure_vector_kgc(geom)
