Main features
What GPSMan does when in graphical mode:
- GPSMan keeps lists of data items (waypoints, routes, tracks,
polylines and groups) whose information can be written to and
read from text files, or, except for polylines,
got from
and put into supported GPS receivers;
- GPSMan lets the user create new data items, as well as modify or
delete those already defined; groups (sets) of data items are very
helpful in keeping and classifying the existing information, as well
as in the selection of information to be processed;
- GPSMan makes conversions of
- routes into tracks;
- tracks into routes,
tracks or polylines,
by
keeping a certain number (fixed by the user) of track points;
polylines into tracks;
- tracks into a waypoint taking the averages of the latitudes,
longitudes and altitudes of the track points;
- waypoints in a group into a waypoint taking the averages of their
latitudes, longitudes and altitudes;
- GPSMan records real-time track logging information that can be
displayed on a moving map and used to create a track (that may be
then converted into a route
or a polyline
);
- GPSMan makes computations of,
- for waypoints: distance and bearing to another
waypoint, nearest waypoints (in fact, distances and bearings to all
other waypoints ordered from nearest to furthest), clusters of
waypoints with given centres,
- for routes: distances, azimuths and differences in altitude
between consecutive points, total distance, and enclosed area
(under certain conditions),
- for tracks: distances, differences in time, speed and azimuths
between consecutive points, cumulative distance and altitude at
each point, total distance and average speed
for the track, distance from first to last point, maximum distance
from first point to any track point;
- GPSMan can make a map to scale, using one of a choice of projections,
showing waypoints, routes, tracks
and polylines
;
the map can be saved or printed in
Postscript or other graphics formats if the Img
Tcl/Tk
library is available; images may
be used as background for the map and geo-referenced; waypoints can
be represented in different ways (any combination of symbol and name
or comment); an animation of the movement along the real-time track
or of a recorded track can be shown on the map;
elevation graphs, as
side-views or perspectives, of
routes and tracks can be plotted and saved or printed in Postscript
or other formats if Img
is available;
speed and climb rate graphs for tracks can be plotted, saved
and printed in a similar way;
- GPSMan allows for data items to be searched by:
- patterns matching the item name, comment and/or remark,
- distance to a given waypoint or location (given by its
coordinates), for waypoints and tracks,
- symbol, for waypoints,
- waypoints, for routes,
- start date, for tracks.
- GPSMan provides conversion between different position formats
(latitude/longitude in DMS, DMM or DDD, and several grid coordinates,
including UTM/UPS) and/or different datums; there is support for
user-defined datums, ellipsoids, projections and related coordinate
grids.
- GPSMan allows the user to change its configuration, providing a
choice of languages (Dutch, English, French, German, Indonesian,
Italian,
Spanish
and Portuguese in the current
distribution), and accepting new values for parameters related to the GPS
receiver, default settings, and concerning interface appearance
(colours, dimensions, positions).
What GPSMan does when in command-line mode:
- GPSMan makes availability and connection checks.
- GPSMan provides information on its version, the supported
protocols, data file formats,
projections, coordinates
transformations, datums, and available commands.
- GPSMan connects to the receiver, gets data or the real-time log
and stores them in a file.
- GPSMan reads data from a file in a user selected format,
connects to the receiver and transfers the loaded information to
it.
- GPSMan reads data from a file in a user selected format and
writes it to another file in another selected format.
GPSMan prints the projected coordinates of a point using
a given projection.
- GPSMan produces an image information file from geo-referencing
data.
- GPSMan executes Tcl/Tk scripts and scripts made up of GPSMan
commands.
