Files in Other Formats
GPSMan can import and/or export data in the following formats:
- EasyGPS
export format; only for importation of waypoints;
- Fugawi
export format; only for importation of waypoints;
- GD2;
for importation only;
- GPStrans;
GPX;
for importation and exportation;
- GTrackMaker;
for importation only; all waypoints, routes and tracks will be
read from the file, the other information being discarded;
IGC;
for importation of tracks only; each file corresponds to a
single track; there is a parameter for selecting either
GPS altitude or barometric (pressure) altitude; positions in 2D
fixes are discarded if the latitude and longitude are 0 and
there was no previously accepted fix, or if there is a change of
more than 5 degrees either in latitude or longitude from the
previous fix; a valid fix after a discarded one will be marked
as a segment starter in the track; the track name will be that
of the file without any extension unless the name is in use;
the remark field indicates that barometric altitudes was used if
that is the case, and the file name if it is not the track name;
a datum number of 999 is taken to mean "WGS 84";
- MapGuide
text (not XML!) export formats from 2002 or 03/04
versions. Warning: undetected errors may occur if the
version given when opening the file does not correspond to that
of the file.
This format is only for importation of
routes; each file corresponds to a single route that will be
split in several ones according to the maximum number of
waypoints in a route; a number or identifier for the (first)
route can be given when opening the file, as well as, a comment
and a remark; if the original route yields more than one route, a
suitable remark will be added to each route after the first one;
- MapSend;
- Meridian,
only in the Magellan variant;
NMEA real-time log;
only in the Garmin variant, and only for for importation of tracks;
each file is taken as a track;
OziExplorer waypoints and tracks files;
only for exportation of waypoints (not more than 1000 per file)
and tracks (one per file);
- Shapefile
if the gpsmanshp
Tcl/Tk library is available;
version 1.1 or later is
required
; a single data type is kept in a
file as described in the gpsmanshp documentation; data can
be stored in 2 or 3 dimensions and GPSMan
needs the
following parameters when reading/writing a file in this format:
dimension, position format (that must consist of a single number for
each coordinate), zone (for grids), datum, distance unit and
altitude unit. Warning: use of a UTM zone
with points belonging to another zone may produce
conversion errors that are not reported. In GPSMan versions
before 6.1 there
were two different names for 2 and 3 dimensions, the position
format, the datum and altitude unit were assumed to be decimal
degrees (DDD), "WGS 84", and metre.
The
information on
track or polyline segments is not saved to Shapefile files. With
gpsmanshp version 1.1, routes, tracks and polylines can be
read from Shapefile polylines or polygons.
