table_getNearestLocation | R Documentation |
Returns a tibble of the known locations from locationTbl
that are closest to the vector of target locations specified by longitude
and latitude
. Only a single known location is returned for each
incoming target location. If no known location is found for a particular
incoming location, that record in the tibble will contain all NA
.
table_getNearestLocation( locationTbl = NULL, longitude = NULL, latitude = NULL, distanceThreshold = NULL )
locationTbl |
Tibble of known locations. |
longitude |
Vector of longitudes in decimal degrees E. |
latitude |
Vector of latitudes in decimal degrees N. |
distanceThreshold |
Distance in meters. |
Tibble of known locations.
