First, i want to thank you the authors for this great gps tool. My question: after extensive search on google ans sourceforge, i do not find pertinent information about the use of google maps for map downloading. Has somebody an answer ? Thank you jm Renard |

Hello, I am writting a GPS navigation program and I would like to use the gpsylon java library. I have a problem with the GPSNmeaDataProcessor. For same reason the readMessages() method does not work as expected. It some times reads EOF characters (data == -1) even though the data stream from the GPS has not terminated. The same happens in the readGarbage() method. I also think that sometimes it does not process correctly the NMEA sentences from which it extracts the ERROR (both vertical and horizontal ) information and the ALTITUTE information. In these cases it does not generate any ALTITUTE or ERROR events. But I have not debugged that problem yet so I do not know what part of the code does not work properly. I think that the problems are related to the following sentence $GPRTE,1,1,c,*37 because this was the last sentence sent by the GPS before the error conditions were created. This sentence was generated by the eTrex in DEMO mode. I am using 2 GPS: a) GARMIN eTrex ( the yellow one ) Software version 2.14. I use it in demo mode connected to the PC through the Serial port. b) EMTAC BTGPS-S3 Blutooth GPS. The emtac site says that it supports NMEA-0183 V2.2 I used the EMTAC while driving around with a laptop and no ALTITUDE or ERROR events were generated. Any comments regarding this problems are wellcomed. Best regards, Napoleon Maou |

This message is posted CC to the mailinglist as I think that despite of the german language, it might be interesting for others as well. Hallo Michele, Manuel, Hanspeter, Cristina-Mihaela, Samuel (2x)! Wow! Das ist ja super! > Nun haben wir gedacht, bevor wir etwas beginnen möchten wir zuerst > mit Ihnen Kontakt aufnehmen um Ihre Meinung zu hören. Bitte per "du", wenn es euch nicht stoert. > Unsere Vorstellung wäre es, einige Route-Features zu implementieren > sowie Bugfixing zu machen. > Zu den Route-Features haben wir uns folgende (provisorische) Ziele gesetzt: > > * Routes > > * Define, name and manage routes > * Download maps for a given route in a given scale Super, das wollte ich (und andere) eh schon lange! Ihr koennt euch evtl. das modifytracks plugin ansehen, da gibts schon so was aehnliches. Ist allerdings nicht perfekt, bzw. bin ich garnicht sicher, ob es wirklich funktioniert. > * Automatic map download (when zooming) gute idee, auf das bin ich noch garnicht gekommen. Wahrscheinlich deswegen, weil ich immer gleich Karten in allen moeglichen Auflösungen runtersauge. Zum automatischen Kartenrunterladen: Da muss man sich überlegen, ob man nicht fuer jede Zoomstufe ein fixes Raster für Karten einplant. Dadmit laesst sich leichter feststellen, ob man eine Karten schon hat, bevor man sie nochmals runterlaedt. Druück ich mich da verständlich aus? > * Use fixed overlay grid Was ist das? > * Zoom in/out: > > * use mouse wheel > * right mouse button > * scale slider gefaellt mir.

Hmmm.. musste jetzt selbst code lesen :-) In der Theorie sollte es per Menu (GPS/Simulation Mode) gehen, kann aber sein, dass das ein bug ist. hab ich schon lang nicht mehr gebraucht. wenn ihr da einen Fehler findet, bin ich euch dankbar!

Zuerst möcht ich mich mal bedanken, dass ihr mir helfen wollt! Find ich super! Ich hab jetzt ein bisschen ueberlegt, was man alles machen könnte, bzw. was auch längerfristig Sinn macht. * Routen definieren und sie mit Garmin up/downzuloaden. Speichern/laden von Routen * Plugin Architektur: Plugins können im Moment zuwar Menueinträge eintragen, aber nicht beliebige: Es wäre gut, wenn Plugins sich in bestehende (Unter)Menus eintragen könnten oder neue Menus machen könnten. * Alles Mögliche sollte "pluginisiert" werden. Auch die Layers, die im Moment fix "verkabelt" sind (z.B. LocationMarker Layer). Z.T. ist das nicht viel Aufwand, nur die Konfiguration und die Menueinträge müssen beachtet werden. * Simulation Mode, NMEA File Mode geht nicht mehr? * Google Maps als Kartenquelle: Da es ja seit kurzem für Europa bei Google Maps super Karten gibt, wär das eine gute Quelle. Das gpsdrive Projekt hat ein perl script, das angeblich google maps runterladen kann. Ist natürlich die Frage, welche Projektion google verwendet! * GUI: Ich hätte gerne, dass die Benutzeroberfläche auch von Plugins erweitert werden kann. Als Beispiel wäre der Statusbar (im Fenster ganz unten), wo sich ein Tachometer-Plugin reinhängen kann. Cool wäre es auch, wenn man diese Teile dann per drag and drop im Fenster verankern kann, rumschieben (dock oben/unten/links/rechts) oder als extra Fenster aufmachen kann. Ich hab schon ueberlegt, das Framework von jedit zu verwenden, das kann das alles schon. Jedit ist halt nur ein editor :-) * Die GPS Daten sollte auch als plugin implementiert sein. D.h. dass man nicht nur ein gps als Location-Quelle sondern auch andere Daten verwenden kann (z.B. WLAN Hotspots mit Signalstärke triangulieren, etc.). Das ist grundstätzlich nicht soo schwierig, das einzige Problem ist, das die Parameterübergabe, mit der in Gpsylon ja das GPS configuriert wird. Das müsste man irgendwie loslösen, bzw. eine Plugin-Schnittstelle für Commandline Parameter machen. * LocationMarker: im Moment liest der Layer ja nur eine Datenbank. Praktisch wäre evtl. wenn man mehrere dieser Layer (sollte vorher ein plugin werden) verwenden könnte und damit mehrere verschiedene Datenbanken verwenden könnte. * Dokumentation: das readme.html sollte in mehrere Files aufgeteilt werden. Das würde die Übersichtlichtkeit erhöhen und man könnte leichter zusätzliche Pluginbeschreibungen reinnehmen. * MapManager: der kann im Moment keine Karten löschen. Diese Funktionalitaet ist noch nicht implementiert. D.h. er muss die maps.txt Datei auch schreiben können, nicht nur lesen. * MapManager: kann nur mit einem Kartentyp umgehen. Wenn man jetzt mehrere, verschiedene Kartentypen verwendet, hat man da ein Problem. Sam Benz hat einen neuen Kartentyp inkl. Projektion für das Swissgrid implementiert, der hatte gerade vor kurzem das gleiche Problem. Er wollte (oder konnte :-) aber nicht verschiedene Typen gleichzeitig verwenden. Muss man auch überlegen, wie man das mit mehreren Karten macht, die eine verschiedene Projektion haben. * Im Moment muss man ja rxtx für die serielle Kommunikation vorher installieren. Das liesse sich ändern, wenn man direkt die Bibliotheken per Parameter für die JVM übergeben kann. Das geht per "-D java.lib.path". Für Linux/Unix ist das kein Problem. Ein gpsylon.sh shell script gibts schon (da fehlt nur noch der -D parameter), der dann auf die lib/Linux rxtx libraries verweist. Damit braucht man rxtx nicht mehr zu installieren, sondern kann einfach starten. Für Windows scheitere ich im Moment noch dran, dass die !"§$%& Batch files nicht herausbekommen, in welchem Directory sie selbst liegen und damit keinen relativen Pfad auf das lib/Windows (gibts noch nicht) Verzeichnis setzen können. Habt ihr da eine Idee? Ein gpsylon.bat, das auch per doppelklick funktioniert und auch aus einen anderen Verzeichnis aufgerufen werden kann. So, das waren mal meine Ideen! Ihr könnt natürlich machen, was euch lustig ist. Praktisch für mich, und einfach für euch wäre es aber, wenn ihr möglichst viel von eurem Code als eigenes Plugin implementiert. Ist natürlich nicht immer möglich. Aber z.B. die Routenerweiterung laesst sich glaub ich komplett als eigenes Plugin implementieren. Damit verhindern wir ein code-chaos. Ich CCe dieses Mail auch an die gpsylon mailingliste. Damit haben wir die Chance, dass sich auch andere Leute beteiligen können und die Liste wieder etwas belebt wird. Bitte nutzt auch die vorhandene Infrastruktur von source forge (bug reports, Diskussionen). Sprache optimalerweise Englisch, wir können diesen Thread aber auch gerne auf Deutsch weiterführen. Evtl. sollten wir den Thread hauptsächlich über die Mailingliste fortsetzen (wenn ihr alle subscribed seid), dann bekommen auch immer alle alle infos. Ich habe auch Sam Benz (noch ein Schweizer) auf die CC Liste gesetzt, er hat in letzter Zeit auch Code beigesteuert und ein paar Ideen gehabt. Ich freue mich schon auf eine fruchtbare Zusammenarbeit mit euch! schöne Grüsse in die Schweiz Christof -- --------------------------------------------------------------------------- Christof Dallermassl chr...@da... --------------------------------------------------------------------------- |

Hi! Marc Rechte sent some patches for the garmin code, so I did some cleaning up in this part of the code (the gpsylon application did not changed at all). I fixed the watchdog again (it has been broken for a while as it seems). As my garmin legend is broken, I could only test with an old garmin summit. If you could do any further tests (download, upload, position, etc.) with your garmin devices and report the results, I can ensure that the code works (and if not we can fix it). Please check out the latest version from cvs (version number must be 0.5.2cvs20050421) for the new code! happy gps'ing Christof -- --------------------------------------------------------------------------- Christof Dallermassl chr...@da... --------------------------------------------------------------------------- |

No, DestinationLayer had a mouseClicked function, so I just used that. But
that means that if it is done as a separate plugin one would have to switch
between the navigation and the destination plugin when only one mouse mode
can be available at a time. Isn't that suboptimal?

It didn't display values below 100 with one decimal. I changed the function
to:
public String getValueString(double value)
{
if(value > 100.0) {
return(String.valueOf((int)Math.round(value)));
} else {
int v = (int)Math.floor(value);
int v2 = (int)Math.round(value*10);
String s = v+"."+(v2-v*10);
return(s);
}
}
The implementation can properly be done better; but this works. Feel free to
put it in. Its in UnitHelper.java:313 here.

Hi Allan, Allan> It's some time ago now; but I'll see if I can sum up the changes.

If you write a new mouse mode, the mouse-keys wont interfere with other mouse modes, as only one mousemode is enabled at one time. But as you wrote, you'll think about putting all into a plugin, you'll have to do that anyway. I think, as more and more mousemodes are available, we should create a button bar (right under the menu) where all the icons go that should be available to the user (download, distance, zoom, ...).

I already have a basic layer here, that allows the user to draw tracks and routes, but I have not had time to add it to gpsylon in a usable matter. And I'm not sure, if I want to add new features, as long as some old ones are not finished (no possibility to choose tracks to upload to gps, no way to remove maps, ...). But at the moment, my time is very limited and so I cannot work on gpsylon as much as I wanted. Allan> Ok.

Hi! the new prerelease should make the plugin interfaces stable (more or less) and it should fix the problems windows users had with windows paths in the properties. As I'm locked out of sourceforge at the moment, CVS is not uptodate - please use the source distribution for the latest source. Sorry about that! Everyone is highly welcome to add plugins to the distribution! Look into the software design document for details. regards, Christof -- --------------------------------------------------------------------------- Christof Dallermassl / Institute for Information Processing and Computer cd...@ii... / Supported new Media, Graz University of Technology --------------------------------------------------------------------------- Dino Developer Community - be a part of it - http://www.dinopolis.org |

hi! finally I managed to add the source to the cvs repository. The build.xml files are not yet perfect do not perform everything they should (e.g. cannot create source/binary distributions), but they should be ok for compiling, running and creating javadoc. I was working on a plugin architecture these days, and it started to work. the plugins (create the jars with "ant bin_dist") and copy the jars and the lib/java (if any) directory either to ~/.gpsmap/plugins or to a plugins directory on the same level as the classes directory (or on the same level as the gpstool.jar file). It is not yet perfect, but I think it is a good start. any comments are welcome!!!! regards, Christof -- --------------------------------------------------------------------------- Christof Dallermassl / Institute for Information Processing and Computer cd...@ii... / Supported new Media, Graz University of Technology --------------------------------------------------------------------------- Dino Developer Community - be a part of it - http://www.dinopolis.org |

Hi!
I just wanted to tell you, that I'm on holiday over christmas and wont
be back until jan, 5th or so.
During this time I won't (or rarely) read my emails, so do not be
disapointed when I do not answer right away.
I'll post a new release which holds some minor bugfixes:
2002/12/19: bug fix (reported from Jun Li): if the map layer was
deactivated, no maps were displyed on startup.
Added service (plugin) functionality for "save as". At the
moment, jpg and png is supported. A svg service is done,
but needs some other jars, and I dont know how to include
them easily.
2002/12/14: double click in search list (markers) jumps to chosen
entry.
postgresql works now (confirmed by Thomas Mueller)
2002/12/13: fixed bug that ignored the gpsd port settings (default
port was always used) (reported by Adam Coyne)
2002/12/12: fixed bug that prevented correct writing of location
marker file (instead of the comma, its deciaml value (44)
was written.
2002/12/11: fixed bug reported by Jun Li in
org.dinopolis.gpstool.util.FileUtil: the filenames were
not correctly created.
2002/12/08: added javadoc to src distribution
added design document to documentation
merry christmas and a happy new year!
Christof

Hi! Thomas Mueller and me thought about adding plugins to GPSMap. The first problem to solve is the "how add a plugin". After some searching I found out, how the javax.imageio and the javax.sound handle this. Any jar file in the classpath may contain a META-INF/services directory. This directory contains files that are named like the interface they extend and the implementing class(es) are written line-by-line in this file. For a longer (german) explanation, see http://javangelist.snipsnap.org/space/Plugin or http://java.sun.com/j2se/1.4/docs/guide/jar/jar.html#Service Provider or http://java.sun.com/j2se/1.4.1/docs/guide/sound/programmer_guide/appendix1.html The problem is, that sun uses the undocumented class sun.misc.Service for this. An example may be seen in the source of javax.imageio.IIORegistry . If we decide not to use the sun.misc.Service class, we could also find the service-files by calling ClassLoader.getResources("META-INF/services/x.y.z"); what do you think? Advantage of this approach is that no registration of plugins has to be done, just add the jar file in your classpath. If we find a way that this works even without jar files, its perfect! So defining a couple of plugin interfaces (Thomas made some suggestions, like import (maps, markers, ...), export, gpsdata-in (nmea), ...) Any suggestions???

Hi! This release fixes some minor bugs and provides a search facility for location markers. In combination with imported geonet data, it is possible to search for even smalles villages and center the map to the search results. This was a feature I was missing a lot and finally I had time to add it! I hope, you enjoy it as well! mit freundlichen Gruessen Christof -- --------------------------------------------------------------------------- Christof Dallermassl / Institute for Information Processing and Computer cd...@ii... / Supported new Media, Graz University of Technology --------------------------------------------------------------------------- Dino Developer Community - be a part of it - http://www.dinopolis.org |

Hi! I just released a new version of gpsmap: 0.4.11 The following changes were done: ---------------------- snip ------- snap ------------------------- added login dialog for other dbs than hsqldb (e.g. mysql). if the mysql database exists (mysqladmin create <dbname>), the tables should be created automatically. Added lots of keyboard accelerators and menu mnemonics. Removed the scale combobox from the status bar (better? solution in menu, accessible directly via accelerator keys). sorted the categories in the category dialog, added level of detail to be edited. Import of compressed geonet files is possible (zip) Dialogbox if maps.txt file is not found. Some tests under win98se. added concept of "level of detail" to categories, made a dialog to choose the categories to show changed the creation of the MapBean a bit, so the projection does not change that often anymore (everytime it changes, the location marker layer searches in the db for markers. ---------------------- snip ------- snap ------------------------- have fun...

I only a very quick test - but I can't get it to work.
When I start gpsmap I am asked if I want to create the missing database,
when selecting 'Yes' I get lot of exceptions, the last one is:

After restart of gpsmap I get the message about the missing database
again.

Hi! I just released the latest version of gpsmap (0.4.9). The biggest change is the location marker handling. They are stored in a database now. This allows to select specific categories to be displayed and others not to be displayed. The categories have icons, so the visual feedback should be nicer than before. Apart from this, I fixed some bugs and improved the preferences editor.

Hi! I just released a new version of GPSMap (0.4.8). Finally, GPSMap is able to handle location markers (aka waypoints). At the moment, they are stored in a simple file (comma separated), but database access is prepared. Another feature that may be handy: the content of the window may be stored as jpeg/png file. Any bug reports or feature requests are welcome! cheers, Christof -- --------------------------------------------------------------------------- Christof Dallermassl / Institute for Information Processing and Computer cd...@ii... / Supported new Media, Graz University of Technology --------------------------------------------------------------------------- Dino Developer Community - be a part of it - http://www.dinopolis.org |

Okay you're right, that's impossible (especially if you want to run GpsMap on a PDA). > Second: is it not enough to be limited to the current screen? Well, > I'll think about it. The problem is: if you zoom out, all you see are waypoints. If the window shows europe, 5000 waypoints will be shown. That's why I thought about the distance. So I think there are two possibilities (they can be combined): 1. define a threshold for every category when to show these waypoints; speedtraps only below 1:25000, restaurants below 1:10000 and so on 2. define a raster; when adding waypoints to the database you can save the raster where the waypoints are in; when displaying waypoints show either all waypoints or only waypoints in the current raster und the surrounding ones (configurable if all or not) That way no calculation is necessary, you only have to select the squares. > Thomas> o icons for every category > clear > > Thomas> Sometimes in the future? > Thomas> o warn if you are coming near a speedtrap (and tell the speed > you're > Thomas> allowed to drive -> the speed has to be saved) > I thought about that, too :-) I even tested speech output (there is a > free java package for this - works, but did not test much).

Hi Thomas! You wrote the bug report: "I left gpsmap having 1:10000 scale; on restart it show the 1:10000 map, the dropdown box shows 1:50000 as scale; wenn I select 'Follow me' gpsmap selects the 50000 map, when I start moving it selects the 1:10000 map again but the dropdown box still shows 50000" I tried to do the same as you did, but it works for me (only difference, I simulated the movement with the simulation mode (shift + left-mouse sets the destination, select simulation mode in menu). But I cannot see any changes in the scale. The dropdown box does not reflect the scale currently used. it is mainly for quickly changing the scale (without the page-up/down keys). BTW: I rewrote the graticule layer, so it should work now. cheers, Christof -- --------------------------------------------------------------------------- Christof Dallermassl / Institute for Information Processing and Computer cd...@ii... / Supported new Media, Graz University of Technology --------------------------------------------------------------------------- Dino Developer Community - be a part of it - http://www.dinopolis.org |
