DESCRIPTION

27       GpsDrive is a car (bike, ship, plane, foot) navigation system.  It will
28       display  your  position  on  a  map, record your track, and a number of
29       other handy functions.
30
31       GpsDrive connects to a GPS receiver and displays  your  position  on  a
32       zoomable  map.  The  maps are auto-selected depending on your position.
33       You can choose the preferred map scale, which the program then tries to
34       match  from  the  available maps. Basic worldwide maps are provided and
35       tools are included to help you add your own localized maps.
36
37       GpsDrive will work with the vast majority of GPS receivers which output
38       NMEA  sentences  to  a  serial  device, and any USB GPS binary protocol
39       known to the Gpsd software, which handles  the  back-end  communication
40       for  GpsDrive.  See  the  Gpsd  website (http://gpsd.berlios.de) for an
41       extensive list of GPS receivers known to work with  that  software.  In
42       most cases your GPS will "just work".
43
44       "Gpsd is a service daemon that monitors one or more GPSes attached to a
45       host computer through serial or USB ports, making all data on the loca‐
46       tion/course/velocity  of  the  sensors available to be queried on a TCP
47       port of the host computer. With gpsd, multiple GPS client  applications
48       (such  as  navigational  and  wardriving  software) can share access to
49       GPSes without contention or loss of data."
50
51       You must install and launch gpsd before running GpsDrive.

DISCLAIMER

56       Do not use GpsDrive as a primary means of navigation!
57       Keep your eyes on the road and hands on the wheel.

OPTIONS

67       -?, --help
68              Displays a short help message.
69
70       -e, --embedded
71              Don't show the GUI; for use in external GTK apps.
72
73       -f, --force-position
74              Force display of position even if the GPS fix is invalid. Before
75              a GPS has a fix it often reports its position as 0,0. And if  it
76              has  lost  a  fix  some  makes of GPS will repeat the last known
77              position together with a fix-is-bad indicator.  Normally  (with‐
78              out this flag) GpsDrive skips plotting these points.  Useful for
79              debugging.
80
81       -i, --ignore-checksum
82              Ignore NMEA checksum. (risky, only for broken GPS receivers)
83
84       -p, --explore-mode
85              Start in Explore Mode. This will let  you  explore  around  your
86              maps independently of your GPS position (or lack thereof).
87
88       -s, --nosplash
89              Don't show the startup splash screen.
90
91       -t, --touchscreen
92              Set  this  special  mode if you only have a single mouse button,
93              for example when using GpsDrive on a touchscreen display.
94
95       -v, --verbose
96              Displays some basic debug information to  the  terminal  as  the
97              program runs.
98
99       -x, --use-DBUS
100              Use  DBUS for communication with gpsd; this disables socket com‐
101              munication.
102
103       -A, --alt-offset=<OFFSET>
104              Adjust the displayed altitude by adding this value.
105
106       -B, --gpsd-server=<SERVER>
107              Server name of  the  NMEA  server.  You  can  connect  your  GPS
108              receiver  to a remote host which is running gpsd and display the
109              position on your local machine.
110
111       -C, --config-file=<FILE>
112              Set this if you wish to use an alternative configuration file.
113
114       -D, --debug=<LEVEL>
115              Set the debugging level. A level of 0 will show no debug  infor‐
116              mation, while a level of 100 will show a lot of debugging infor‐
117              mation.  If you have problems or program crashes, set this  high
118              enough  to  display relevant information send this output to the
119              authors.  See also the BUGS section below.
120
121       -F, --friends-server=<SERVERFILE>
122              Select a friends server to exchange  position  information  with
123              other  people, e.g. friendsd.gpsdrive.de.  You can also set this
124              from the Preferences/Friends  menu.   You  can  start  your  own
125              friends server with the included friendsd program.  More details
126              are in the FRIENDSD section below.
127
128       -G, --geometry=<GEOMETRY>
129              Specify the window geometry, e.g. 800x600.
130
131       -M, --gui-mode=[car|pda|desktop]
132              Set GUI mode. The default layout is 'desktop'. Car modes sets up
133              the  display  in a fullscreen mode suitable for use with a small
134              LCD touchscreen. PDA mode dedicates even more screen real-estate
135              to the map, controls are hidden behind tabs.
136
137       -N, --nmeaout=<FILE>
138              Set  a serial device, PTY master, or file to send NMEA sentences
139              to.  This is useful if you use GpsDrive in  simulation  mode  to
140              provide other GPS applications with test data.
141
142       -S, --screenshot=<PATH>
143              Take  auto-screenshots of different GUI windows then exit. Image
144              files will be saved to the specified path. Don't touch  gpsdrive
145              while this is running!
146
147       -T, --run-test

CONNECTING A GPS RECEIVER

161       Start GPSD
162       This  program  runs as daemon in background and provides a server which
163       sends the GPS data on port number 2947. You can download and learn more
164       about gpsd at http://gpsd.berlios.de.
165
166       Once  gpsd  is  running you can monitor the raw NMEA output of your GPS
167       with telnet localhost 2947 and after the connection is made hit  the  R
168       key  to see the NMEA sentences. You can use the xgps program that comes
169       with gpsd for a more comprehensive test.
170
171       If you have connected a GPS receiver, and are successfully  communicat‐
172       ing  with  it,  you  will see GpsDrive's signal strength indicator turn
173       from red to green. By clicking on the signal strength indicator you can
174       open  the  Satellite  Info window which will show you information about
175       the satellites in view.
176
177       To calculate a 2D position the GPS must have at least 3  satellites  in
178       view.   To  calculate  altitude  you  need  at  least 4 satellites. The
179       antenna of your GPS receiver must have free sight to the  sky,  so  you
180       cannot  expect  to  use  it indoors. More satellites gives you a better
181       accuracy.
182
183       If your receiver can not see enough satellites with  a  usable  signal,
184       the  signal  level  indicator  is red. If your signal is ok and gives a
185       valid position, the Satellite Info indicator is green.
186
187       You can restart the connection to gpsd in the GPS tab  of  the  Prefer‐
188       ences menu.
189

191

USAGE

193       Start  GpsDrive as a normal user with: gpsdrive from your shell, if you
194       want another language see the LOCALISATION section.
195
196       On some distributions you may find a "GpsDrive" entry in your Gnome  or
197       KDE menu.
198
199       It  is  important  that  you have installed GpsDrive as root, so it can
200       find the necessary files.  Don't start GpsDrive as root!
201
202       You can use GpsDrive without a  GPS  device  connected.   GpsDrive  can
203       automatically  start  in  Simulation mode if no working GPS receiver is
204       connected and no gpsd is running. The GPS  signal  level  indicator  is
205       replaced with a message indicating the mode.
206
207       In  simulation  mode the pointer will move by itself on the map towards
208       the target position. It may be switched permanently on or  off  in  the
209       Preferences menu.
210
211
212
213   Modes Of Operation
214       GpsDrive operates in three modes:
215
216       Normal mode:
217       This  mode  is entered if you have a GPS receiver connected. The cursor
218       is at the position your GPS receiver sends.
219       Black and red arrows show your position  on  the  map.  The  red  arrow
220       points  to  your  selected  target (aka "Bearing"), and the black arrow
221       shows the direction in which you are moving (aka "Heading").
222       When the GPS is not sending a valid position the arrows blink.
223
224       Simulation mode
225       If GpsDrive does not find a GPS receiver when the  program  starts,  it
226       shows the last known position and the cursor will move towards the tar‐
227       get you set. You can set the target with a right-mouse click on the map
228       or  by selecting a waypoint from the Find dialog. The target appears as
229       a cross-hair and is available in all modes.
230
231       Explore mode
232       In this mode you can temporarily change the cursor position for looking
233       around  and jumping to other positions (e.g. for downloading maps). The
234       lat/lon position shown in the dashboard is that of  the  current  mouse
235       position.
236       This mode is selected by ticking the "Explore mode" box in the Map Con‐
237       trol window, or if you "Jump to POI" in the Find window.  The Jump but‐
238       ton  simply  jumps  to  the current target, so it is useful to move the
239       target to a waypoint/POI first by selecting one from the list.
240       In this mode GpsDrive does not show your real position  and  the  posi‐
241       tioning arrows are replaced with a box.
242       You  can  relocate  your position with a simple left-mouse click on the
243       map or with the arrow keys (including diagonals on  the  keypad).  Maps
244       are automatically scrolled or load the next map when you click near the
245       border.
246       To leave Explore Mode untick the "Explore mode" entry in the  Map  Con‐
247       trol  window,  or  middle  or right-mouse click on the map. If a right-
248       mouse click is used the  target  is  reset  to  that  position  in  the
249       process.
250
251
252       You can change the preferred map scale with mouse wheel, or if there is
253       no mouse wheel, with Shift-left and right mouse click.  This works from
254       any mode.
255
256       Please  have  a  look  in the Help menu in GpsDrive to learn more about
257       available keyboard shortcuts and mouse functions.

MAPS

262   OpenStreetMap Maps
263       GpsDrive now supports OSM maps with the help of  the  Mapnik  renderer.
264       To activate this mode you have to build GpsDrive with the Mapnik option
265       enabled.
266
267
268
269   Map Download
270       You can easily download maps from the internet with the Download  tool.
271       This  is  found in the Options -> Maps menu. A preview of already down‐
272       loaded maps near to the current preferred mapscale are shown as  yellow
273       rectangles  drawn over the map. The area to be downloaded is drawn as a
274       green rectangle over the map. Reposition the area to be downloaded with
275       a left-mouse click. Map scales given in the GUI for OpenStreetMap tiles
276       are only approximate, the true scale at the selected latitude  will  be
277       calculated  when  the map is downloaded - this can vary by up to 50% at
278       high latitudes and is a limitation of  the  popular  Web  Tile  method.
279       LANDSAT  maps  use  a  WMS  server  and  will match the requested scale
280       exactly.
281
282       If you have Mapnik set up you can also use the gpsdrive_mapnik_gentiles
283       utility  to pre-render maps of varying scale directly from your PostGIS
284       database.  There is also a program called gpsfetchmap.pl provided  with
285       GpsDrive  which  can be used to automatically download a series of maps
286       covering a larger area from a number of online map servers.
287       Please consider the copyright information and terms of service  of  map
288       providers if you want to use their maps!  Do not misuse this service by
289       downloading more maps than you need!  You will risk  being  blocked  by
290       these servers, and possibly cause trouble for the GpsDrive project.
291
292       If  you must access the internet via a proxy server, set the HTTP_PROXY
293       or    http_proxy    environment    variable    to    a    value    like
294       http://proxy.provider.com:3128  where 3128 in this example is the proxy
295       port.
296

298
299   About Maps
300       GpsDrive stores an index of your maps in a file called  "map_koord.txt"
301       in  your ~/.gpsdrive/maps/ directory. You can use another directory for
302       your maps if you like, to change this set the appropriate directory  in
303       the Preferences menu.
304
305       Here is a sample of its contents:
306
307       top_WORLD.jpg 0.00000 0.00000 88226037
308       map_file0000.gif 53.60751 10.01145 3160000
309       map_file0001.gif 43.08210 12.24552 3160000
310       map_file0002.gif 49.81574 9.71454 7900000
311       map_file0003.gif 47.72837 14.46487 592500
312
313
314       The  first  column is the filename, then comes the latitude, the longi‐
315       tude and the scale of the map. Typical scales for all of  Europe  might
316       be 1:10,000,000, and 1:100,000 for a town. To see detailed streets in a
317       city, choose a scale like 1:10,000 or 1:5,000.
318
319       You  can  figure  out  the  exact  "scale"  factor  by  meters/pixel  *
320       2817.947378.   The  2817 number is derived from some ancient screen dpi
321       converted into pixels/meter.
322
323       GpsDrive selects the map with the best scale for your position. So  you
324       will  want  to  get maps of different scales. e.g. You should have maps
325       for Europe, Austria, and Vienna if you want to drive in Vienna.
326
327
328   European decimal place:
329       While the decimal points in way.txt must always  be  a  dot  ('.'),  in
330       map_koord.txt '.' or ',' are possible. If you download maps from within
331       the  program,  GpsDrive  writes  the  map_koord.txt   respecting   your
332       LC_NUMERIC setting.
333
334
335
336   Can I use other maps?
337       You can also use your own (self drawn, scanned, exported from GIS, ...)
338       maps.  The maps must be in PNG, JPEG, GIF, TIFF, or another common file
339       format  (the format must be recognized by the gdk-pixbuf library).  The
340       lat/long coordinates you write into the "map_koord.txt"  file  is  mea‐
341       sured  at  the center of the map. The map must have a size of 1280x1024
342       pixels!
343
344       Important! The maps must be  named  "map_*"  for  UTM-like  projections
345       (lat:lon  = 1:cos(lat)) and "top_*" for lat/lon Plate carrée projection
346       (lat:lon = 1:1). The prefix is given so  that  gpsdrive  knows  how  to
347       scale  the maps correctly. Alternatively the maps can be stored without
348       prefix in subdirectories of $HOME/.gpsdrive/maps/ which end  in  "_map"
349       or  "_top". The georeferencing information (center coordinate and scale
350       factor) for the maps in those subdirectories must be  recorded  in  the
351       main  "map_koord.txt"  file,  typically stored in the ~/.gpsdrive/maps/
352       directory. To avoid distortion, anything more  global  than  1:150k  to
353       1:500k should use "top_*".
354
355       Beware if you are using an image originating from a map projection with
356       a significant deviation between true north  and  the  map  projection's
357       local  +y  direction (known as the Convergence Angle). GpsDrive assumes
358       that true north is always directly up! i.e. the Central Meridian of the
359       map  projection  is located at the map tile's center. For some map pro‐
360       jections and areas of the country this can be a really  bad  assumption
361       and your map will be significantly rotated. This effect is most visible
362       at map scales covering a large area. This does not affect lat/lon maps.
363
364       There is an "import assistant" built in. Use it to import your non-geo‐
365       referenced maps. If can be found in the menus under Options -> Maps.

WAYPOINTS AND POI

370   Importing waypoints
371       The manual way:
372
373       You  may  create  a  file "way.txt" in your ~/.gpsdrive directory which
374       looks like:
375
376       DFN-Cert                53.577694    9.991263 FRITZ
377       Finkenwerder            53.541765    9.842541 AIRPORT
378       Fritz_Wohnung           53.582700    9.971390 FRITZ
379
380       The rows are: {label latitude longitude waypoint-type}.  The label  may
381       not  exceed  80  characters  or  contain spaces. Use underscores (_) in
382       place of spaces, these will automatically be converted into  spaces  by
383       the program.  A blank label is denoted by a single underscore.
384
385       Latitude  and  longitude  may  be  in decimal degrees or in the form of
386       DDDdMM'SS"[NSEW] or DDD:MM:SS[NSEW]. Seconds or minutes and seconds may
387       be   omitted  or  in  decimal  form.  Thus  the  following  are  valid:
388       42d30'55"N, 75:30.6425W, -46.25.  In fact the delimiters  can  be  any‐
389       thing except numbers, ".", or spaces.
390
391       You may omit the waypoint type.
392
393       Following  the  waypoint-type  are  (optionally)  three space separated
394       zeros, a proximity radius (in integer meters), and a comment.  Comments
395       follow  the same space/underscore rules as label names, and are limited
396       to 255 characters.
397
398       You can create any number of way-*.txt files  and  chose  between  them
399       from the Preferences menu.
400
401       There  is  no need to create the way.txt file yourself, you can add the
402       waypoints with GpsDrive using the "x" key. See the Help menu.
403
404
405
406   Add new waypoints
407       Waypoints created by GpsDrive will be stored in a SQLite database  file
408       locacted at ~/.gpsdrive/waypoints.db.
409
410       You can add new waypoints in two simple ways:
411
412       o To add a waypoint at the current (GPS) position simply press CTRL and
413       RIGHT-mouse-click. You can also press the x key for this.
414
415       o To add a waypoint at the mouse position, simply press CTRL and  LEFT-
416       mouse-click. You can also press the y key for this.
417
418       In  the popup window give the waypoint a name (spaces will be converted
419       to underscores) and choose a waypoint type (see  below  for  predefined
420       waypoint types).
421
422
423
424   Waypoint icons
425       At  the  moment  there a three different icon themes available, but not
426       all have distinct icons for every type. You can choose  the  themes  in
427       the   Preferences   menu.    The  possible  themes  are:  "square.big",
428       "square.small" and "classic".
429
430
431
432   SQL support
433       For managing a larger number of waypoints  SQL  support  is  essential.
434       Don't  be  afraid, SQLite doesn't need much in the way of resources, is
435       very fast, and makes the management (including  selection  of  waypoint
436       types)  of  the  waypoints  much easier. In SQL mode you can select the
437       waypoints to display in the Preferences menu.
438
439
440

ROUTES

442       A route is a list of waypoints. GpsDrive guides you from  one  waypoint
443       to the next on the route.
444
445       You  can  add waypoints to a route using the Find waypoint (select tar‐
446       get) window. Find some POIs, then open the Route  Listing  window  with
447       the Edit Route button in the Find window or from the button on the main
448       window. When you click on waypoints in the the  Find  window's  Results
449       list they will be added to the Route List. Click "Start Route" when you
450       are ready to begin your journey. It is also possible to import  a  com‐
451       plete route from a GPX file.
452
453       You  can  add comments to a waypoint which will be spoken by the speech
454       system and also be shown in the map window as scrolling text.
455
456
457   Comments for routes
458       To add comments create a file with the same name as the waypoint  file,
459       but  change the suffix to .dsc, i.e way-trip.txt and way-trip.dsc, then
460       enter comments in the way-*.dsc file in the manner of:
461
462       $waypoint_name Text which is displayed and spoken
463
464       $next_waypoint_name Some more text
465
466       Example:
467
468       $Fritz_Wohnung Hier wohnt Fritz, der  Autor  von  diesem  Programm.  Er
469       freut sich auf Besuch und eine Einladung zu einem saftigen Steak.
470
471       $Hubertus Hier wohnt Hubertus, ein Freund von Fritz.
472
473       There  is  no limit of the length of the comment. It is important is to
474       start the line with '$name' and the comment on the following line.
475
476
477
478   Route planning
479       There is no shortest-path route planning feature at the moment. We  are
480       keenly watching developments over at the OpenStreetMap project for uti‐
481       lizing software such as pgRouting and DGLib.

KISMET support

486       GpsDrive supports kismet.  Kismet is a 802.11b wireless network  (WLAN)
487       sniffer.  If  you have kismet running, gpsdrive will detect it when the
488       program starts and show new WLAN access points in real-time on the map.
489       It  is  necessary to use SQL mode when using GpsDrive with Kismet. WLAN
490       access points which are already stored in the SQL database  from  prior
491       war-drivings  are ignored. If you have enabled GpsDrive's voice output,
492       you will hear information about the newly found access point.
493
494       For more details have a look at the README.kismet file.
495
496
497

LOCALISATION

499       The program will display messages in English, German, French,  Italian,
500       Dutch,  Dansk,  Hungarian,  Slovak, Swedish, Turkish or Spanish if your
501       language is set either with LANG or LANGUAGE.  LANGUAGE  overrides  all
502       other  settings.  Call  "locale"  to see the settings and call "set" if
503       LANG or LANGUAGE is set. For German do:
504
505       export LANGUAGE=de
506       and then call gpsdrive in this shell.
507
508       You can also start it with the line LANGUAGE=de gpsdrive  without  set‐
509       ting the language for the shell.
510
511       Sometimes it is necessary use LANG instead of LANGUAGE.
512
513       If  your  own  language  isn't  available,  please contact the GpsDrive
514       Development Team if you want to make the  translation.  No  programming
515       experience is necessary!
516

518

SPEECH OUTPUT

520       If  you want speech output you have to install speech dispatcher and at
521       least one of the supported speech synthesizers (festival, espeak, ...).
522       See http://www.freebsoft.org/speechd for information.
523
524       For German output you can use espeak or the German festival from
525       http://www.ims.uni-stuttgart.de/phonetik/synthesis/index.html
526
527       If you have a functional festival software call it as server with:
528
529       festival --server
530
531       When you start GpsDrive it will detect a running speechd and speak some
532       status  information.  When speech output is enabled  an additional Mute
533       button is available to switch off sound output.
534
535       GpsDrive tries to use the correct language for  your  locale.   If  the
536       voice  used  is  not correct, you can choose another one in the Prefer‐
537       ences, if installed.
538
539
540

FRIENDSD server

542       A server program called friendsd comes with  GpsDrive.  It  acts  as  a
543       server for coordinating the position of your friends. After enabling it
544       in the Preferences menu you can see the position of all GpsDrivers con‐
545       nected to this server.
546
547       You  will  see the position of your friends as a car symbol on the map,
548       including the name, time, day of week and the speed of their last  con‐
549       nection.   The  blue  arrow  shows  the last reported direction of your
550       friend.
551
552       The time is transmitted as UTC, but shown on the display in your  local
553       time, so it is also correct if your friend lives in another time zone.
554
555       The  server uses port 50123 (UDP), so be sure that you open the port in
556       your firewall. The server needs no root privileges and should run as  a
557       normal  user  or  a special user with no privileges. The server has NOT
558       been tested for security.
559
560       There is a friends server running on friendsd.gpsdrive.de, you can  try
561       it if you enable it in the settings menu.
562
563       You  can  also send messages to other mobile targets (Options/Send Mes‐
564       sage)
565
566

MAILING LIST

569       The primary means of support and coordination  of  program  development
570       happens on the GpsDrive mailing list.
571
572       Information about subscription and a searchable archive can be found at
573       http://www.gpsdrive.de/support.shtml.

BUGS

578       Please send bug reports to the development team! If we don't know about
579       them we can't fix them and then they remain unfixed.
580
581       File  bug  reports in our tracker at http://bugzilla.gpsdrive.de/.  You
582       will need to create yourself a SourceForge account at that site, it  is
583       rather  painless and only takes a minute. This ensures you get feedback
584       about the bug and we can communicate with you if we need further infor‐
585       mation.
586
587       Please  report the version (gpsdrive --version), screen size, platform,
588       and as much specific information about how to reproduce the bug as pos‐
589       sible.   Whenever  possible cut and paste exact error messages and take
590       screenshots.  It is helpful to run gpsdrive for a minute  with  the  -D
591       debug level option set high and send us the output.
592
593       If  GpsDrive  crashes  with a SegFault, we will need a backtrace of the
594       program as well. Assuming GpsDrive was built with debugging symbols and
595       the  binaries  were not stripped of them, create a backtrace by running
596       the GpsDrive the GNU debugging software as follows:
597
598         gdb `which gpsdrive`
599
600       Inside the debugger do:
601
602         run (if you use command line arguments place  these  after  the  word
603       run)
604
605       When you get the SegFault type in:
606
607         bt full
608
609       and  send  us  this output. This gives us an indication of exactly what
610       the program was doing when it broke.
