Yep
in sql
I end up with x2 sql files per map source for my system of doing things.
One sql file is for my whole state in 0-13 zoom level. And the other file for select areas of my state in zoom 14+
I can just add more of the map to the 14+ sql file as I find more spots where I want more zoom (so for example if i want more of XXX town in a higher zoom, I just select that area from within locus, check the boxes for zoom 14,15,16,17. And then in the "download type" option dropbox I select "External map sql type" and point it at the existing 14+sql file so I can just add extra data to that file instead of creating a new one, prevents downloading the same tiles twice for no gain
Thats my system anyway. Originally I had about half a dozen different files for each map source, but I ended up with alot of overlaping duplicate areas in the files so I went with a 2 file system for each map source based on zoom levels to avoid the duplicate tile issue. I used MOBAC to join the existing half dozen sql files together to match my new system (it was alot of arsing about and a little confusing joining SQL files in MOBAC but I managed it
)
