Well, this probably means the OSM coverage is still lacking in some areas if it is only 7 GB

All the available OVI maps data (which includes POIs) takes up about 5.5GB of space.

Hey Martin:

Happy Nameday :O)

OK, thanks to this I was able to really see what's going on, quite helpful.

Autorotation depends on python-osso but modrana doesn't have it as a depend. You should update the package info. Once python-osso is installed, works no prob.

With the partial crash, I think I see what's going on and why it gets stuck:

Code:

**log: stdout redirected to (this :) log file
** making a list of available tracklogs
*  using this tracklog folder:
tracklogs/
*  does it exist ?
True
*  there are 6 tracklogs available

and it basically goes on and on with the same instruction.

I'm in Russia now and using Mapnik as the source, it quite nicely has all the streetnames in Russian. I assume however that espeak does not know how to handle this UTF-8 text, since the lang isn't specified and so it seems it gets stuck on reiterating the same instruction. Nothing comes out of the speaker, i.e. nothing is said, and the blue box doesn't appear.

I was successful a couple of times in getting the blue box with instructions to appear, I assume this must've been where the directions were not in UTF-8, for a lack of a streetname in Russian or what have you. Nothing was said though. And then when I hit reroute, it'd say 'rerouting' and then get stuck, probably on the Russian directions.

If this is the case and programming in the language support would be too big of a task, I'd just recommend hacking in to skip saying the streetnames if they are in UTF-8 and just say 'turn' 'in' '80' 'meters' so that it'd still work and not have probs.

You must've the same probs in Czech though...

One would hope. The nice part is that it would allow one to customize the route in a GUI drag/drop environment on line, then send that specific route (with turn by turn) to the phone. Handy for those routes where one must re-route the default Google route because it uses a seasonal road that's closed, or has holes larger than your car.

And yes, I live in a place with both multi-lane urban highways, and rural seasonal "roads" that have 2m+ divots in the road. Lucky me, eh?

And that's the million dollar question. For now, stage 1 will be make it work and see how quickly we can pump tiles. Then we can look at what stage 2 will be.

Who knows, it may just work fast enough to be a raw server with minimal (ram) tile caching. Or, it could be so slow that it's unworkable completely. Won't know till it's setup.

Yeah... Not too bad. But eatting 1/4 of your free space to have local maps kinda sucks. I'm sure I can break it out by major area (Americas, Europe, Australia, etc), which will at least help cut it in half for most people. Can't wait to start on this project now... but have to wait to get free time to do so. Soon though!

Hi Martin,
Awesome application, big credit to you for the time and energy that you are putting into this !!

I have been trialling ModRana in the past few days based on your advice (and PM), and brilliant assistance from another thread on Mapping, I have loaded Nautical maps as one of my repositories and use this (overlayed to Google Satellite) whilst out on the water to record tracks, mark fishing spots/POI's and understanding the depth/terrain of the current position (based on map data).

Some Questions:

1) How is the screen blanking controlled/determined? What conditions/setting would keep the screen on? (probably userguide related so let me know if I can find this already somewhere)

2) I have a POI DB with 2044 marks. Navigating through these easily is difficult in Modrana (long list). Is there an easy way to keyword search the POI's loaded or Display the nearest POI's to your location from the db ?

I'll keep testing and let you know of my thoughts. I'm thinking a 'Boat' mode could be cool, it would seem this is easily achieved with your customizable interface.

Well done, and thank you !

Install the simple brightness applet, it has option that allows you to keep the screen on.

I think I have fixed the issue in the current unreleased version:
I looked through the routing API definition and found how to request directions in more languages, including Russian.
So I can get native directions in some language + make espeak use the same language for voice output. Google provides directions in more languages than Espeak supports. I have therefore added only languages that are supported both by Google and espeak.

These languages will be supported:

Code:

Catalan
Chinese(Cantonese)
Chinese(Mandarin)
Croatian
Czech
Dutch
English
Finnish
French
German
Greek
Hindi
Hungarian
Indonesian
Italian
Latvian
Norwegian
Polish
Portuguese(Brazil)
Portuguese(European)
Romanian
Russian
Serbian
Slovak
Spanish
Tamil
Turkish
Vietnamese

I have faked my current location to Moscow and tried to do some routing, no crashes so far + all the Cyrillic letters were displayed without problems, just the espeak Russian voice output could be better

That reminds me:
The espeak output quality varies per language, some languages may be barely usable, others are quite good.

The only problem was espeak reading Czech place names with english pronunciation, which is often quite funny

But it worked even before without problems, most probably because our alphabet is basically just ASCII + čřžýáíéůú.

It might not be so difficult to implement, as it means basically just analysing incoming SMS for the right keywords and then loading the appropriate route (provided the message contents are not encrypted, etc.).
But it seems to be USA-only, so I would not be able to directly test/debug it there in Europe

The directions API used by modRana supports adding waypoints, but it is not yet accessible from the GUI.

There are already some extracts available from Cloudmade and other sources.
They are quite nicely available for individual countries and continents , on the other hand a (possibly resource intensive ?) import from the OSM XML to the tileserver database would be needed.

Wow, modRana being used on a boat, well that's awesome

I wonder how long before someone reports about using it in an aircraft

Something like "leave backlight on" for starters, and more advanced stuff like turning the screen on when approaching a turn later

(probably userguide related so let me know if I can find this already somewhere)

Well, that's unfortunately true

The modRana project wiki is currently horribly outdated, I just haven't got to updating it yet

BTW, I someone wants to add something like a walkthrough, feature description, etc. to the modRana wiki, just send it to me and I'll add it

Just how did you add so many points ?

Well done, and thank you !

Why not

BTW, modes work like this in modRana:

each mode can have its own map GUI settings
each mode can have its own widgets settings
current mode is considered when when routing (foot mode -> walking directions, etc.)

Do you have any nice boat mode specific optimizations on your mind ?

I'll give it some thought.....started to put something together......might be some 'nice to haves' but I think the basics deliver a lot already..

But in the maybe pile:

Speed indicator (knots)
Moon phase (info screen or search)
Tides (info screen or search)
Weather (info screen or search)
Distance (point to point)
'Spot x' button takes you immediately to new POI based on GPS location (Rather than Menu >> POI >> New >> Based on position. A one click POI :-)
POI alert/sound (as hands might be other things, an alarm of approaching POI or eSPeak ;-) eg POI near Fishing spot 1

This is great, however please note that the language of streetnames can vary from the directions language. You're probably aware of it, but for instance in the Moscow case, I'd not want the instructions in Russian, and might prefer them in English, but the streetnames are in Russian, so should be pronounced in Russian...

Well, at least that's what I assumed it was getting stuck on, i.e. somehow deciphering the Russian names...

Check out the Device State section of the wiki and osso_test_device_blank_pause.py for a way to keep the screen on.

On an unrelated note, I'm anxiously awaiting an offline routing mode.

Agree. There are different ways.
1. Use tracklogs which are close enough (10m?) to the start and end points as route.
2. Remember routes received from Google and reuse them.
3. Ask user to download OSM vector maps for wanted region and then use the vector maps for offline routing.
