Some time ago I've posted a note about creating some custom maps for maemo-mapper from BSB nautical charts: http://talk.maemo.org/showthread.php...&highlight=bsb.

I've made a bit of development since then. A new set of scripts are written in Python, so they can be used with Windows as well. The scripts requirements are: the Python (tested with v. 2.5.2 and 2.6.6) with the Python imaging library, the GDAL tool set (tested with v. 1.6.3 and 1.7.2), optionally numpy package and pngnq tool

Here is how it's all implemented:
1) bsb2gdal.py or ozi2gdal.py -- creates geo-referenced GDAL .vrt file, optionally cropping the raster;
2) gdal4tiles.py -- creates a tile set tree directory for every chart using gdal2tiles.py from GDAL; (gdal2tiles.py also creates a couple html files, so the result can be checked with a browser).
3) tiles-merge.py -- sequentially merges a few tile sets in a single one to cover the area required;
4) tiles-opt.py -- compresses png tiles into a palleted form using pngnq tool;
5) tiles2mapper.py -- creates a sqlite3 file from a tile set tree. This file you then just copy into a maemo-mapper maps directory. You'd also need to create a reference to this file at the maemo-mapper repository settings.

For options list use "--help"

There is also kml2gdal.py script which helps geo-referencing any png or jpeg raster using Google Earth: you import a raster into the Google Earth stretch it accordingly, export it as kml file, then kml2gdal.py creates a GDAL .vrt from it.

For poi2mapper.py functionality see http://talk.maemo.org/showthread.php?p=810365

Below are the latest version of the scripts

UPDATE!

Please ignore these files. A new version of these scripts are available from here: http://code.google.com/p/tilers-tools

Thank you very much for the converter. Here is tiles2mappero.py script (made from your tiles2mapper.py) which can be used to produce folders suitable for mappero (former maemo-mapper). Mappero's repository/tiles settings dialogs seem to be very buggy, so this far I've failed to add new repository to it, but at least I've succeeded in replacing cached files in existing subdirectories of $HOME/MyDocs/.maps.

Cheers fionbio! Have you tried tiles-merge.py --gtiles. At the 1st glance it looks like it does what you needed, doesn't it?

Actually it's possible just feed these directories a http server (I tried boa), to download them into some other mapping application which is able to fetch google tiles.

BTW I understand there are a couple of ports of the original the maemo-mapper for n900: https://garage.maemo.org/frs/shownot...elease_id=3406 and http://shmuma.livejournal.com/24660.html

hi vadp,

this is output when i try to convert map with ozi ogf2 and tiff in folder.Filenames in .map file are the same as in folder.Any suggestion where to look for error.
Thank you,
Thomas

Hi Tomas. Can you run it with -d switch? BTW do you have gdal binaries installed and they are in the PATH?

A newer version of kml2gdal.py was added to the 1st post. It has a better datum definition for the Google Earth.

yes , i try but same , gdal binaries are installed .

output is here:

Hi Tomas, it looks like you need a more recent version of python for this: 2.6 or above.

update: I've made another version of the script, so see if it's any better for you (remove .txt from it's name)

Hello!
I have jpg maps with .ogf2 and .map.
At first I use ozi2gdal.py to get GDAL .vrt. After that tiles-from-gdal.py to get tiles tree with some zoom levels and html's with overlay. If I check the result in browser - it ideally fits google-map or openstreetmap.
What I can't figure out is right url format for maemo-mapper, I use:
http://myserver/maps/%0d/%d/%d.png like on openstreetmap, but in server's logs I see it tries to get other tile numers I have in tree. Zoom levels are ok, but x and y differs...
For example: my generated tree contains 8/145/177 and it's identical to oss 8/145/78 and google's x=145&y=78&z=8

Hi ksb! I think you can try tiles-merge.py with "--gtiles" option
