How to create Garmin BirdsEye JNX maps

[bogi]

2) Открываю MOBAT2JNX и что туда вписывать?

Please see the Example call in the 1st post of this thread.
For simplicity, you can also create file mobat2jnx.bat containing the only line:
mobat2jnx.exe %1 -sas
and then to drop your cache directory on the bat file.

я вот по этой мануале делал

That's nice manual, although it describes quite different procedure to create JNX map than my opening post of this thread.

Let me compare these 2 ways:

1) Using MOBAT2JNX
- Only one addon tool needed: MOBAT2JNX
- MOBAT2JNX directly accesses GMT tilestore, so there is no need to generate map from the tilestore in SAS.Planet
- No real restriction for size of the generated JNX map. MOBAT2JNX sequentially reads the GMT tilestore and is able to generate set of JNX files, if the number of tiles within one JNX file exceeds the limit (50000 tiles). Currently 250 JNX files can be processed by Garmin devices. So using MOBAT2JNX you can generate really big maps.

2) Using map2jnx, as described in the above link
- It is necessary to generate map in SAS.Planet (ECW + worldfile). I don't know if SAS.Planet has limit on size of generated ECW. Even if there is no limit, it takes some time to generate the ECW map.
- The procedure uses 2 additional tools:

GlobalMapper to generate geotiff from ECW
map2jnx to generate JNX from geotiff

I mean the MOBAT2JNX way is simplier.

metallizer, вы разобрались со значением -jnxscale? Что оно означает?

Now, after a half year, it is much easier to set the visibility scale for each JNX map level by the JNXCustomizer tool:
http://dl.dropbox.com/u/36140/jnxCustomizer1020.exe
The tool uses the same scale levels, as you see on the display of the Garmin device, so it is much easier to use it.

I don't know how many SAS.Planet users own a Garmin device with support of BirdsEye JNX format (Colorado, Dakota, Oregon, Montana, GPSMAP62, EDGE800 and few others).
If there would be an interest, I have clear idea how to integrate JNX map generation into SAS.Planet.

My idea is based on this post:
http://gpsunderground.com/forum/garmin- ... #post65410
Very shortly: MOBAT2JNX now supports KML file, generated by SAS.Planet using area selection -> Export -> KML (for Google Earth). The KML file with absolute paths to cache tiles can be used as parameter for MOBAT2JNX. This way not only rectangular selection, but also polygonal selection is supported.
An example MOBAT2JNX call (http://gpsunderground.com/forum/garmin- ... #post65605):
mobat2jnx selection.kml -tilelist -sas
The switch -sas is used only to understand the relevant part of the <href>...</href> lines within the KML:
<href>D:\SAS.Planet\cache_gmt\Dolomiti-4land.it\z14\5808\8730.png</href>

JNX file generation could be integrated into SAS.Planet for example by one of these 2 possible ways
a) To allow to configure an optional command, which could be executed automatically just after the KML file generation
b) To implement JNX file generation as explicit option in SAS.Planet, either in the Stick tab, or in the Export tab. In this case tilelist would be generated and external MOBAT2JNX command would be executed. The generated tilelist could have the format of KML (for Google Earth), but it would be sufficient if it would contain only a pure list of absolute paths to cache tiles.

I mean it has no sense to fully implement JNX file generation into SAS.Planet, because the JNX format is not so simple. There are specialized external tools available and there are people, who are fully involved into creating of these tools. It's much easier to use an external tool, than to try to implement the JNX geenratiom within SAS.Planet.

Приветствую!

SASPlanet users can create JNX maps from SASPlanet tile storage of type "Google Maps Tiles".

Это значит, что не с любым кэшем саса будет корректно работать?

[garl]

ага. только с GMT . хотя имея исходники прикрутить родной тип кэша делов на 5 минут.

Здравствуйте!
А как в MOBAT2JNX задать Map name и Group Title?
Спасибо!

Сохраняем выделенную область в KML.
Конвертируем полученный файл с помощью программы в JNX. http://narod.ru/disk/36070903001/KML2JNX.rar.html

Правда точность привязки в сохраняемых файлов KML из SasPlaneta меня пока не радует

[garl]

и хоть бы кто выдал конвертер в Дэлфёвых исходниках ...

[AlexWhiter]

Конвертера нет, но есть модуль для чтения и записи JNX-файлов.
Забирать тут.
