The most commonly used file formats generated by GPS receivers and tools are:
- CSV: The first line contains the attribute names, the subsequent lines the data in temporal order. The following parameters are available:
longitude are the geographic coordinates in WGS84 degree (mandatory).
seq_num specifies the temporal order (optional). The lines must be sorted by temporal order.
timestamp indicates the time and date, for example
speed_mps indicates the speed in meters per second (optional).
speed_mph reflects the speed in miles per hour (optional)
speed_kmh indicates the speed in kilometers per hour (optional).
speed indicates the speed in meters per second (optional and deprecated).
heading indicates the heading in degrees clockwise from North (optional).
- GPX: Each trace point can have the following information:
- Coordinates, for example
<trkpt lat="48.0289225" lon="-4.298227"> (always present), WGS84 degree
- A timestamp, for example
<time>2013-07-15T10:24:52Z</time> (optional), time zone UTC
- Elevation, for example
<ele>102.5999</ele> (optional), meter above the WGS84 ellipsoid
- HDOP, for example
- Speed, for example
<extensions><speed>21.9432334</speed></extensions> (optional), meter per second
- NMEA: The information from the $GPRMC records is used. If an NMEA trace does not contain $GPRMC records, then the $GPGGA records are used.
- KML: Either <Placemarks with <Points> or <Placemarks> with <LineStrings> can be submitted. Folders with multiple traces are not supported.
In order to get a response without timeouts, trace sizes should not exceed 100,000 points or 15,000 kilometers.
