Get all sites within a given distance of a point location

Source: R/get_sites_within_radius.R
get_sites_within_radius.Rd

[Experimental] retrieve all sites within a given distance from the center point (in coordinates lat, lon), and in the (optionally) specified elevation range.

Usage

get_sites_within_radius(
  lat = 39.1386,
  lon = -8.33305,
  distance = 1,
  elevation_range = c(NULL, NULL),
  show_map = TRUE
)

Arguments

lat

latitude of radius center

lon

longitude of radius center

distance

distance from point (actually it is in degrees for a limitation of the endpoint)

elevation_range

min and max elevation in meters

show_map

logical print a map with retrieved sites (default is TRUE)

Value

list of deims_id, distance from given coordinates
