Hi,
you have to count that SQLite map format is taken from application RMaps. Many people used this app so I decide to be compatible with this. Little mistake anyway all works now fine ...
so, about format:
- zoom level is usually computed as 17 - z, but some map providers use different numbers
- zooms column? What is problem with this? Values in "zooms" are from SELECT DISTINCT z FROM ... This takes really long time on bigger maps so I'm storing this value separately
- 's'? don't know it's purpose in RMaps but I finally use it for storing time, so it's number of hours since 1.1.2011. I use it to determine validity of maps for limited time
- and yes .. they (x/y) are same
clear?
