Dear Gabor,

please read the complete thread. It is mentioned several times I guess. The library used is mapsForge. There you can find the tutorials on how to create your own maps using mapsForge's mapsfilewriter plugin and osmosis.

I would recommend to set the max value instead of the min value or at least to set both. I think that 600m could be a little few for larger maps.

So better use something like (replace the value to fit your RAM and bittiness):

Code Select Expand

set JAVACMD_OPTIONS="-Xms600m -Xmx2000m"

Hm, I use osmosis 0.39 with 8GB settings and mapsforge writer 0.2.3

I'm on linux 64bit by the way.

I was using a fresh download from geofabrik yesterday. Did you increase the JAVA memory option for osmosis?

I tried it again with netherlands and I got a big white square in the middle. If I zoom in a lot I can see the details but for most of the zoom-levels there is just white. Is that your problem, menion?

Hm, I've converted Netherlands ca. 6 weeks ago without any problem. Did you download it from geofabrik?

Yes, nearly all of my PCs are Linux based. To be more precise, this was running on my server with Core i5 3,6 Ghz and 16GB RAM.

But it shouldn't be a big difference on windows. But maybe you need a 64Bit system because of memory limitations.

here you can download my generated ...

Hi supermaz,

can you please explain, how you generated the Germany map without these failures? Maybe someone (me?) could generate an updated map.  :mrgreen:

Thanks in advance

Hi,

I just followed the tutorial for the osmosis mapsforge mapfile-writer plugin: http://code.google.com/p/mapsforge/wiki ... terOsmosis

I downloaded the PBF file from geofabrick and converted it using osmosis:

Code Select Expand

osmosis-0.39/bin/osmosis --rb file=germany.osm.pbf --mapfile-writer file=germany.map type=hd
Make sure to modify the osmosis bin file and set the correct java opts:

here is my line:

Code Select Expand

JAVACMD_OPTIONS="-Xmx8000m -Djava.io.tmpdir=/daten/temp/tmp

+1 for me!

Ouch, I thought it would be an OR criteria. Record if the last point is 5s or 5m away. Wouldn't this make more sense?

For the unnecessary points I use prune on the exported GPX files which has functions to automatically reduce the number of points without loosing accuracy.

Wouldn't it be better to have the user select the maps that's are searched for auto-load? Maybe the user can check more than one map in the map selection screen.

For me it doesn't bother. It was just what came to my mind.

From a developer point of view: Why don't you just load the track into the "editor" and treat it as it would just have been created? What's the difference between a track "on editing" and "after editing"? Seems to be easy for me.

Maybe it's just a matter of merging two or more images and then displaying the final image. Then you would only need the additional memory temporary for each tile.

I'm just doing the exercise to create a bike computer custom screen I will rise the text font sizes so that you can see it better on biking. If I'm done, I will upload it here.
