I haven't started working on it yet. You may freely change it - and performance optimisations are always welcome.

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

Late V0.27-4 release announcement :)

What's new ?

patch for better handling of imperial units by Gkuenning - thanks ! :)
fix overlapping labels on height profile with imperial units
modRana now has a profile folder in /home/user/.modrana
configuration files are now in the profile folder
- which means modified configuration files should no longer be overwritten at upgrade (not tested :) )
tracklogs are now in MyDocs/tracklogs
cleanup of example tracklogs
properly use os.path.join in place of simple concatenation
general refactoring and code cleanup
remove GUI source files from installation package (~40% package size reduction)
postinst cleanup should bring faster installation (no chmod needed anymore, yay :) )

Also, modRana is taking part in this years MeeGo coding competition. :)

I have selected just MyDocs/tracklogs, becuase:

it is visible for mass-storage (unlike .maps)
is not using an application specific namespace and other applications can thus share it without needless confusion
in case some users have a folder named like this, modRana never automatically deletes anything inside it, just creates some default folders and adds two example tracklogs

BTW, path to the tracklog folder can be configured in user_config.conf. :)

Mappero stores POI's in .maps/poi.db and modRana supports the same database format, thus enabling sharing (even though it is not on by default). It is possible more applications will add support for POI sharing.

Yeah, configuration files should imho really be in the profile folder, to be kept out of the harms way. Some less experienced users might accidentally delete them if they are too easily available. Also, MyDocs is unmounted in mass-storage mode.

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

Martin,
I don't know if I am missing something, but is it not possible to simply search for a location (by address, postcode city etc), and then to have this location shown on the map?

Currently if I want to do this, I have to use the "address to address" routing functionality, and then follow the blue route line all the way along just to see the map of the end point.

It would be nice if there was an option within the 'search' menu to input a location/address and then be taken to this location. :)

ModRana should create /home/user/.modrana automatically - I rewrote quite a lot of the path handling code so there might be a few bugs.

Please run modRana from the terminal by typing:

Code:

modrana

And post/pastebin the output so I can see what went wrong (there will probably be some errors or exceptions in the output). :)

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

I think I know what the problem is (was).

When running modrana from command line, it says:

cannot create directory, file already exists: '/home /user/.modrana'

however, as I said, I had not seen that directory. So I get into my phone via ssh and I see that it does exist /home/user/.modrana, but I was not able to cd into it because it is owned by the root user:

-rw-r--rw- 1 root root 4740 Jul 25 11:46 .modrana

I tried to get inside that directory, but I do not know why I could not. I thought it was a matter of permissions, but it was not:

Nokia-N900-51-1:/home/user# chmod 777 .modrana
Nokia-N900-51-1:/home/user# cd .modrana
-sh: cd: can't cd to .modrana

I erased it, and after that, I ran modrana again, and now I have the proper .modrana directory:

Nokia-N900-51-1:/home/user# ls -l .modrana
-rw-r--r-- 1 user users 3108 Aug 2 11:08 map_config.conf
-rw-r--r-- 1 user users 2024 Aug 2 12:39 options.bin
-rw-r--r-- 1 user users 5196 Aug 2 11:08 user_config.conf

Curious thing is, I do not remember that I have created that .modrana directory as root.

Here, pastebin before the "workaround", and here, the pastebin after.

You had a file of 4740 bytes and not a directory, that is why you couldn't cd into it. If it was a directory you sould have had a read out something like:

Code:

drw-r--rw- 1 root root 4096 Jul 25 11:46 .modrana

Also as read permissons were set for all users you could have still cd into it if it was a directory.

Now I think I know how it got there:

Code:

# migrate options.bin

if [ -w  /opt/modrana/data/options.bin ];then

  echo "migrating options.bin"

  mv /opt/modrana/data/options.bin /home/user/.modrana

fi

(excerpt from the postinst script)

Notice how there is no / after .modrana ? :D

Well, still better than the bumblebee disaster. :)

I'll release a version with updated postinst shortly (and add a fix that fixes all those .modrana files). :)

Well, I'm not really a database architect - I basically just thought quite a long time about how to make an universal schema and asked a friend who works with databases a bit. :) Well, like this, the lookup and store databases are independent - so when the lookup one is corrupted, it should be possible to regenerate it just form the stores.

Yeah - say we have x=1 y=2 and z=17 -> 1217, also x=1,y=21,z=7 -> 1217 ...
A hash with separators might work though: 1,2,17 vs 1,21,7 - would something like this be usable ?

Also, would it be possible to maintain backward compatibility by adding this new indexes and still storing the old info ? Converting all the existing database files users might already have would be quite a headache and also some developers might be already working on supporting the format in its current form (IIRC the CloudGPS developer, maybe also some others).

There is a version filed in the schema, so it would be possible to do something like this:

1 = current version
2 = old info + new indexes
3 = just new indexes

I think your proposed versioning makes sense. As long as we add any new columns after the existing columns so that if anybody's already using the schema and doing "select(*)" we won't break their code.

Your idea of a hash-like index using separators seems a good idea. My only other thought was to force each of the x,y,z elements to a fixed length (perhaps by adding 1000000 to each, depending on what the biggest number each one could possibly be). But your method makes it more compact.

Then for version 2, your lookup table could be:

Code:

CREATE TABLE tiles (z INTEGER, x INTEGER, y INTEGER, store_filename STRING, extension varchar(10), unix_epoch_timestamp INTEGER, store_tilenumber INTEGER, lookup STRING, PRIMARY KEY(lookup));

CREATE TABLE version (v integer);

CREATE INDEX oldindex on tiles (z,x,y);

For version 3, drop the z,x,y and extension columns as well as the oldindex index.

Version 2 of the tile store could be:

Code:

CREATE TABLE tiles (z INTEGER, x INTEGER, y INTEGER, tile BLOB, extension VARCHAR(10), unix_epoch_timestamp INTEGER, id INTEGER AUTO INCREMENT, PRIMARY KEY(id));

CREATE TABLE version (v integer);

CREATE INDEX oldindex on tiles (z,x,y);

For version 3, drop the oldindex index. You could keep the x,y,z columns in this table for regenerating the lookup table as you mentioned. You could shrink the lookup table a bit more for version 3 by also dropping the epoch_timestamp from it. That would introduce a slight overhead when checking for updated tiles as it would need to be retrieved from the store rather than the lookup. I'm not sure which way would give the best balance of benefits.

So you'd insert the tile in the store first, then retrieve the value of the id column to populate the store_tilenumber column in the lookup table.

Well, I've just sent V0.27-2 to the autobuilder, that does just this :)
check out the updated data storage article for details about the new paths.
In short:

map data - nothing changes, still MyDocs/.maps
POI- nothing changes, still MyDocs/.maps
tracklogs are now stored in MyDocs/tracklogs, old tracklogs should be migrated there automatically
configuration files are now in ~/.modrana

OK, I'll change it to reload the directory once it is listed from the GUI.

I'm looking at this right now. :)

May i strongly suggest not using MyDocs and using dirs located directly under $HOME instead? MyDocs is exportable / mountable, so for example if you have connected your N900 via USB to a laptop maybe for copying some files over, you would not be able to use modRana (or any other SW that does this) at the same time and would have to choose between using the SW or copying files.

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

Hi, I really like this app very much and most of it I like the downloading function. But what I'm currently missing is a layer for public transport. I guess for most countrys these data exist but I don't know whether there is one map that covers all i.e. globe. But if it was possible in any way to add a layer for public transport this would be amazing. Travelling to foreign countries is made much easier if one can use a map with highlighted transportation. Maybe you can have a look at maep which offers this layer but sadly lacks downloading ability.

Another question (I guess this is already answered but I didn't find): Is there an easy way to download all needed tiles for an area externally and afterwards just throw them into correct folder on N900? downloading a bunch of some 20k tiles at once is quite hard. My N900 gets quite hot when using 3G-connection that intense.

I think is the same problem we had before.

mkdir: cannot create directory '/home/user/.modrana/': File exists

Erase that file (as root, using terminal) and try again. Before erase it, it would be useful to attach it here, to see what it has. I erase mine before taking a look at it.

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

The mysterious .modrana file should be renamed options.bin (file that stores current modRana settings) which due to missing / in the postinst script got moved to /home/user and renamed .modrana instead to be moved to /home/user/.modrana/

I have uploaded a newer version - looks like I forgot to first rename the .modrana file before creating the .modrana folder. Let me know if it works now. :)

Thanks for the new schemas & hints ! I'm not really that much into database design, so this is really helpful. :) Now I just need to find some more free time to actually implement this. :D

Other files just need to be in MyDocs:

map data - $HOME only has 2 GB & sharing with other apps
tracklogs - to be accessible through mass storage
POI - sharing with Mappero

ModRana should actually work even when the MyDocs partition is not mounted - tiles would download & display just fine, just would not be stored, tracklogs would be unavailable and it would not be possible to store new POI. Well, I have not actually tested this yet but it should work - or can be fixed to work. :)

@more layers
What is currently precluding adding more map layers (I know about quite a few nice OSM based ones for example) is actually the layer selection method. The current toggle-based one is already barely usable. I'll do something about this and then start adding new layers. :)

You can install modRana or for example GMapCatcher on your PC and then transfer the corresponding tile folders to the N900 (to /home/user/MyDocs/.maps/).

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

Yesterday, modRana V0.28-2 has been released. :)

What's new ?

new patch from Gkuenning
- smart rounding of imperial units for voice output
- fix for 2 turn announcements sometimes following each other at once
- unit conversion module improvements
- improved substitution list & more efficient substitution code
- Thanks a lot ! :)
other improvements:
- geocoding (address search) GUI - finally! :)
  Accessible from "Search->address online"
  The current implementation is fully usable, but please note that some advanced features (asynchronous querying, wikipedia search, geocoding service selection) are not yet implemented. Also, when the search returns > 1 results, this first one is currently used.
- fix for Unicode characters showing only as boxes
- more readable POI search result list & captions
- track recording now works again
- more logically placed cancel button for "in progress" operations
  It is now on the to the right on the blue "in progress" overlay.

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

Why is this software version 0.something?

I think this software is mature enough to have a higher version number. Many people may not try it because 0.27 seems too early developed.

I've been using it for a while now and for me is extremely useful. I live in a country where Nokia Maps does not work well due the lack of map detail and I have to rely on a OpenSource apps like Modrana.

My only complain is how it "talks", but I think it is a eSpeak problem :-)

It is a shame I can not help coding, but if you find it useful, I can translate it into Spanish. I do not know if the texts in modrana UI are hard coded or were thought/designed to be translated.

It's simple - once I add some major feature or improvement, I increase it by 0.01. :) The numbers after - mean mostly fixes and minor improvements.
This numbering originally started on 0.01, 0.04 being the firs released version. Changelogs 0.04-0.27 are on the modRana wiki, BTW. :)

It is currently hard-coded but a proper localization is eventually planed, I just don't know when I'll get to it. :)
In the meantime, I would like to at least localize the voice output. Currently it combines English spoken distance and status messages with turn announcements available in multiple languages - the results sounds quite strange. :)
So if you don't mind, could you translate this few words to Spanish ? :)

I'm afraid there is currently not much information about the GUI outside the (heavily commented) Python source code.
Basically the whole GUI is just a single widget and everything is drawn using Cairo.

strange indeed... and quite funny too :) When I realized that, I changed it back to English, however, the problem is now in the other way: as street names and places are in Spanish, it sounds weird when the English voice speaks them.

I think bumping the version up to 1.xxx would be right at the moment you implement offline routing as that would be a significant stepup in functionality...

That said, offtopic, I still don't understand moving to 3.xxx in the linux kernel with no major stepup from the last 2.6...

2.6.3x basically already was 3.0 seen from the functionality, that's why Linus decided to finally step up the version number. What is more strange that there seems to be no more between stable / unstable kernel versions, like before with even / odd numbering?

(Another example: Firefox 3.7 was functionality-wise already 4.0.)

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

Btw Martin, i checked a bit of the source last night. Some questions:

1) /opt/modrana/os.path seems like Postscript or something? What's this file for?

2) /opt/modrana/nbproject/project.properties lists "platform.active=Python_2.6.6"
As far as i remember, Python 2.6 was a bit of a break compatibility-wise, was it? We have no official 2.6 on the N900; so does make it any difference if you develop with 2.6 under NetBeans instead of 2.5?

3) the theme.conf lists only the icons and the colors. What i also try to achieve is, changing the layout / the shape of the rounded "button" / "info" tiles. which file in /opt/modrana/modules/ is responsible for this?

All times are GMT. The time now is 18:50.
