Restrict results to those from a specified area. Areas must be polygons and be specified as either an sf object, or a 'well-known text' (wkt) string.
Value
length-1 object of class character and atlas_locations,
containing a WKT string representing the area provided.
Details
WKT strings longer than 10000 characters will not be accepted by the ALA- so the sf object or WKT string may need to be simplified.
Examples
Search for records using a shapefile
galah_config(email = "your-email@email.com")
location <- galah_geolocate(st_read(path/to/shapefile))
atlas_occurrences(geolocate = location)Search for records using a Well-known Text geometry (WKT)
