[mkgmap-dev] Tiles missing

Hi Pierre,

welcome to the list! First step is to check if splitter or mkgmap have produced error messages. Post them here if you are not sure.

Betreff: [mkgmap-dev] Tiles missing

Hello,

Sorry my mail format is not as expected but this is the first time I send an email to this mailing list. Be indulgent...

A few months ago, I bought a Garmin GPSMAP 66s (I've already other Garmin devices). I would like to get maps for it without using illegal maps. So, I had a look at OpenStreetMap. The project has made a lot of improvements since the last time I've seen it. So, I'm now contributing to my region.

I was looking for maps for biking but didn't find anything to my taste. That's why I've decided to generate my own maps. I started from OpenTopoMap script which generates maps very close to what I would like. I've generated a map for Belgium and with some adjustments, I get what I want.

Now I would like to generate a map for my next holiday in France but I have issues with missing tiles. Indeed some tiles aren't displayed on my GPSMAP 66s. Whatever is the scale. I've tried the maps from OpenTopoMap and their maps don't have this kind of problem. All tiles are correctly displayed.

I'm using splitter (r597) and mkgmap (r4525). That's not the version used by OpenTopoMap (https://github.com/der-stefan/OpenTopoMap/blob/master/garmin/tools/generate_garmin.sh).

My question is: how can I proceed to find the issue ? I tried to download the same version as OpenTopoMap used but it is not available anymore... I've verified the final france.img file and the missing tiles are well packed in the image.

Thanks,
Pierre Brico
