Re: [Announce] modRana: a flexible GPS navigation system
 

I renamed the directories and started modrana, but still grey screen. Tried downloading tiles, which completed, but I noticed that the only new directory that was written under .maps is monav_data. There is no new OpenSteetMap I or II folders. Modrana is not writting new folders and saving the tiles. Changed to Google maps and still nothing.

@malfunctioning
Yes, I connect to internet then start Modrana and wait till I get a GPS lock before doing anything.

I tried Marble and again, it works well. It wrote a new OpenStreetMap I folder and saved new tiles under 16 folder.

It seems something is wrong in Modrana. I thought I would mention this before I reinstall the application as suggested.

Thanks to all for your help so far.

Re: [Announce] modRana: a flexible GPS navigation system
 

One more thing to try - try renaming the ~/.modrana directory - this is where all modRana settings are stored. If you (re)move it, modRana will recreate it with default settings.

BTW, from the log files it looks like you are using the sqlite tile storage backend, so maybe also try to switch to the files backend. :)

Re: [Announce] modRana: a flexible GPS navigation system
 

This path was initially used for compatibility with Maemo MApper/Mappero - the modRana POI database format is based on & compatible with the Mapper/Mappero one. POI database sharing is off by default but can be enabled in Options->POI->POI storage.

Sure, it definitely makes sense to add a configuration file option to redirecting the POI database storage path, so noted. :)

Yeah, unless someone steps up to maintain it or to develop it further, it is pretty much depreciated at this point. Still, I think I'll try to at least keep it working in its current state on a reasonable effort basis. Also I'm thinking about splitting it to a subpackage as it currently drags in quite a big amount of dependencies even for people using only the GTK GUI.

Re: [Announce] modRana: a flexible GPS navigation system
 

Understood, and thank you very much, M4rtink! :)


I assume you want to maintain at least minimal support so as to not abandon completely that part of your project (which you have devoted many hours to)? When I started using the N900 I naturally gravitated towards using the QDL version of programs like modrana and cuteTube, because I assumed the QDL versions would be newer and more full featured, which then I learned isn't true. I wonder if anybody at all uises modrana QML. The idea of a separate subpackage is good!

MartinK: Any plans connected with Mapnik? You said you were to test it shortly after then.

Re: [Announce] modRana: a flexible GPS navigation system
 

Bingo, it worked. Renamed the .modrana folder and it created a new one and it all works perfectly. Apparently the user_config.conf on old folder was dated 2012, so when the versions were updated, this file remained intact, hence messing the sofware.

Fyi, i did try switching between files and sqlite but it did not help.

I now, finally :), have Modrana working well. Will keep testing and let you know if I find any bugs.

Thank you very much to all for your kind assistance.

Re: [Announce] modRana: a flexible GPS navigation system
 

I've (finally!) started on the actual modRana vector map rendering support. The plan is to have a pipeline like this:

• vector geometry data source
• filtering
• styling
• rendering

The idea is to have the individual stages more or less independent so that different implementations can be swapped out. Also in some cases multiple stages could be covered by a single implementation (this could be the case for Mapnik - it looks like it should be able to cover styling + rendering and maybe even geometry filtering).

At the moment I'm about done with investigating various existing vector data formats. So far none of them seems to be really suitable for what we need - they are often quite undocumented, don't have fast geographic area access (eq. you can't quickly get data for a given geographic area) or require complex dependencies to generate and/read them.

Therefore I'd probably just settle for a semi-custom vector data storage format based on the time-proven modRana sqlite tile database format. Just instead of the png/jpg blobs stored for the individual tiles there will be (optionally compressed) OSM data for the given tile.

Once I have a working data source (which should be hopefully quite soon), I'd like to start investigating rendering backends, including Mapnik. :)

Re: [Announce] modRana: a flexible GPS navigation system
 

It's great! :)

There are lots of vector maps to be downloaded from the OSM webpage for the whole countries (for example this: http://download.geofabrik.de/europe/poland.html). It's particularly useful as you can download the maps for the whole country at once. Will modrana support this?

Re: [Announce] modRana: a flexible GPS navigation system
 

Haha looks like 3d maps are near :D btw able to download whole countries would simplyfy things and are there plans for including here maps ?:)

Re: [Announce] modRana: a flexible GPS navigation system
 

This sounds great.

But I'm moving out... setting up an Xperia Z3 Compact and it will be my main phone by the end of this week.

Martin, thanks again for your work, it was a donation well spent!

If you (or anybody else) goes to Fosdem, let's meet and have a beer.

And I'm looking forward to modRana on Android ;)
(f-droid is a great FOSS repository for Android)
