Re: [mkgmap-dev] resolution, level & levels

Thank you again. I think the fundamental thing I hadn't grasped was that you can't just put a resolution tag on something to cause it to be displayed at that resolution or greater, but that you have to in some sense "create" the level first with the levels specification before you can assign something to that level using either the resolution or level tag.

Yes. I think what's going on is that in the actual bits, there is (more or less) a 3-bit field that specifies the level index, and then a table of 6 levels, so you can't really encode arbitrary levels. I'm not 100% clear on that, but I think the above gives you a useful mental model.
