How to create Garmin BirdsEye JNX maps

[metallizer]

I tested this version. A new options is great. -Trim is work correctly.

But i found a sad bug. In my Oregon map was shifted to the south on all layers.
Checked the older versions - same bug, map is shifted.

My first experiment a week ago was to export Google Maps Tiles from GlobalMapper, as the format of GMT cache was taken from GlobalMapper. I generated JNX using MOBAT2JNX from that cache. In my Oregon, I turned on both the generated BirdsEye (JNX) map and a vector (IMG) map and checked the borders of the JNX map. My generated JNX is not shifted.

Then I tested to generate a JNX file directly from SASPlanet cache of type GMT. The JNX file was correctly generated, but I did not test it in my Oregon. I will test that and let you know.

How did you create the cache you used as input for MOBAT2JNX?
Which map source do you use? Is it correctly defined in SASPlanet? In SASPlanet, when you switch from that map source to for example Google Map or Google Sat, is there no shift?
Can you test JNX creation with some "standard" map source, such as Google or OSM?
If you mean your cache is OK, can you export a small part of your cache and upload it somewhere?
One point or path in KML format from the export area would be helpful to easily find that area in SASPlanet.

I tested that and I experienced no shift.
I assume you have some troubles with your cache.

I exported cache from SAS to Global Mapper format and maked jnx.
Google Maps Tiles has no shift.
Yandex Maps tiles has shifted on south. I think a troubles with export Yandex Maps tiles from SAS to Global Mapper.
MOBAT2JNX works correctly.
Thanks!

Google Maps Tiles has no shift.
Yandex Maps tiles has shifted on south.

Yo bro, have you read our FAQ yet?? http://sasgis.org/forum/viewtopic.php?f=2&t=986

Thanks for link!

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

doc:

You can create multilevel JNX file from Google Maps Tiles cache containing more zoom levels. Then, in Garmin device, each map level disappears at some map scale, as you zoom the map out.

Each map level in the JNX file has defined one parameter, which we call JNX scale. The table on page http://whiter.brinkster.net/JNX.html shows relation between the curent scale setting of Garmin device (you can see it on device's display) and JNX scale seting.

When MOBAT2JNX creates multilevel JNX file from GMT cache, it has to insert the JNX scale parameter for each contained map level. MOBAT2JNX uses some standard settings. With -jnxscale parameter, user can influence, at which map scale the JNX map levels disappear from Garmin device's display. You can assume -jnxscale parameter as an coefficient.

From the MOBAT2JNX readme file:
The default multiplier for calculating JNX Scale factors is 130.2084.
You can also use "set jnxscale=180" in your
batch file or set the permanent environment variable.

So MOBAT2JNX uses default JNXSCALE parameter value 130.2084. If your map level disappear at scale 300m, but you wish it to disappear at 800m, you can try to set the JNXSCALE parameter to 130.2084 * 800 / 300.

For an already existing JNX file, you can still adjust JNX scales of JNX map levels by using the jnxscale utility from http://www.the-thorns.org.uk/mapping/help/jnx.html

Ребята помогите с этой программой MOBAT2JNX. Для тех кто в танке посты выше это дремучий лес.

По порядку что я делал.
1) Зашел в SASPlanet и выделил нужный участок -- Скопировать (выбираю формат GMT GlobalMapper и "куда сохранять" например С:\111 ну отмечаю карие карты и маштабы нужны ). Получаю папку с кэшем.

2) Открываю MOBAT2JNX и что туда вписывать?

я вот по этой мануале делал
только одно но, нужна патченая прошивка навика.
а в остальном удобно ыло бы прилепить экспорт в JNX по аналогии с МЯК, формат же тоже разобран.
