Good decision. I think qtvlm should be allowed to be installed from a menu. The user should be warned with a disclaimer:
qtVlm software is not open source. It is proprietary. Although it reportedly works as advertized, without being able to inspect the source code, it is impossible to verify that it has no malicious actions such as:
1) selling your routes/tracks to various corporations.
2) downloading incorrect/dangerous chart data.
3) reporting computed routes that are not really the optimal route.
4) compromising the security and functionality of other applications.
5) creating a backdoor into your computer
If you understand the risks and wish to continue click YES. Otherwise click NO.
2) Isn't inland waterways in europe already freely available in kap format??
Furthermore, it is not a policy. In fact I started mbtiles native support and got sidetracked. I will get around to it sooner or later. It is not difficult to make it work, but it's a little tricky to make it really efficient and support the transparency and overlay features.
The government gives you files in MBTILES format??
Otherwise I think it's the problem of government, not the file format.

The problem is that opencpn converting the mbtile charts to KAP step is not as easy as you describe... i speak for the most common use in europe... and this is rivers and lakes.1) It is as easy as running the script mbtiles2kaps.py on the mbtiles file
2) Isn't inland waterways in europe already freely available in kap format??
Quote:Mbtiles i have and tiles too but the converting my power of the laptop is not enough.Did the script crash? Please explain.
Quote:as long the charts policy in OpenCPN is so only to support the Kap filesits usefull for a lots of people but not inside Europe and river use...Again, inland waterways are available already.

Quote: From my position i can say the most use for this that the KAP files are only available for Europe its a part to drop and kick OPENCPN. I did need just for the Ijseelmeer to convert nearly 3 months!!!! And result in information is much more less for my needs than in Mbtiles. because here i can simulate a route and download the tiles during this simulation.
We are not lucky in Europe that the government give us for free the KAP files.
From this possition i think OPEN CPN is usefull for USA but not for Europe and i guess its the used file format
