Ok I got the maps into Mappero. I replaced some maps in the cache (google cycling) and now some Nautical maps appear.

Yay !

I just need to experient a bit more now as I have 4 BSBCharts in total (only loaded one) that I want to stitch together to make one set of gtiles.

Is that with tiles-merge.py? I pointed this at the output folder that contains the individual output folders of bsb2gdal but it still creates multiple gtiles subfolders not one.

Also Mappero, has an Auto download tick box that overwrites the cache...woops....probably need to disable that?

So I'm probably going about this in a backward way, but at least my maps are now usable.

I still would like to figure out how I could:

• Add my own repository
• Have the maps be a 'layer' over another map (turn on/off like in output htmls of gdal2tiles.py)
• prevent automatic override ;-)
