Hello,
Thank you for OruxMaps. I like to use it.
I am new in tthis forum, I try to have Michelin France map 1:185.000 (online viamichelin). I successfully created a database with tiles (60 x 60 / 200MB). In Android it shows the map, but it is very poorly calibrated. Some location are just fine, other differ in west/east about 100km!
I looked for calibration data and I found these settings:
Projection : Bonne
Origin : 2°20'14" E / 48°51'36" N (Paris)
Ellipsoide : Plessis
f = flattening = 0.0032400188611
a = axis = 6376523 m
DX, DY, DZ in relation withWGS 84
DX = 118 m
DY = 23 m
DZ = 66 m
I started to understand QGIS and I could see these settings are correct...
Now I would like to put these settings in otrk2.xml. I dont want to reproject tiles due to quality loss. But I cannot find out how to do this. oruxMapsDesktop does not help.
I tried
<MapChunks xMax="60" yMax="60" datum="WGS84" projection="Bonne,2.337,46.8,0.99987742,600000,2200000" img_height="512" img_width="512" file_name="Michelin France" />
but no success
Someone can help me please :-)
Have a wonderfull day with OruxMaps!
Latest RC1 shows .map file in KitKat correct again! Thank you!

Hi,
sorry, but Bonne projection is not supported;
It is a very unusual projection.
orux
Thank you for this fast answer.
So I cannot use this map with GPS. Just for hand-on scolling thou.
Just for archiving the MOBAC bsh script to get viamichelin tiles (completly out of calibration!). Bonne projection!
I like zoom level 12. It is located at (0,0) TL to (60,60) BR tiles.
