gpx
creates XML output in the GPX format (GPS Exchange Format)
from latitude, longitude and time.
gpx(lat, lon, time, file = NULL)
lat |
latitude of the points |
lon |
longitude of the points |
time |
time of the points (optional) |
file |
destination - can be a character string naming the output
file or a connection to use for output or |
The resulting output is in GPX format contining exactly one track with
the specified values (NA
s are currently not supported!). If the
time
value is present then the track entries will include a
time nodes as well. No checking is done on time entries so the user
must ensure that they are exactly of the form
YYYY-MM-DD HH:MM:SS
, assumed to be in UTC.
(Note that OSM requires time stamps to be present in uploaded tracks.)
If file
is NULL
then the value is a character vector
containing the lines of the GPX output.
lat <- c(40.779, 40.777) lon <- c(-74.428,-74.418) cat(gpx(lat, lon), sep='\n') cat(gpx(lat, lon, Sys.time()), sep='\n')
