Get an appropriate UTM CRS for a study area — get_utm_crs • hexsmoothR

Determines the appropriate UTM coordinate reference system (CRS) for a given study area based on the longitude/latitude of its centroid.

Usage

get_utm_crs(study_area)

Arguments

study_area: sf object representing the study area. May be in any CRS; it will be transformed to WGS84 (EPSG:4326) internally for the centroid calculation.

Value

Character string with the UTM CRS, e.g. `"EPSG:32630"` for UTM 30N.

Examples

if (FALSE) { # \dontrun{
library(sf)
study_area <- st_sf(geometry = st_sfc(
  st_polygon(list(matrix(c(-5, 35, 5, 35, 5, 45, -5, 45, -5, 35),
                         ncol = 2, byrow = TRUE))),
  crs = 4326
))
get_utm_crs(study_area)  # "EPSG:32630"
} # }
