 MTSatellite is "realtime" web mapping system for [Minetest](http://minetest.net) worlds.  
 With this system you can play your world and you instantly have an online map of it which

 ## Convert world database into interleaved format
 
 MTSatellite operates best if the block data of the world is stored in a LevelDB database with
 a key scheme called interleaved. With this key scheme you can pick up sets of neighbored blocks a
 lot quicker than with a plain database.
-See [Z-order curve](http://en.wikipedia.org/wiki/Z-order_curve) at Wikipedia for grasping the core ideas.
-MTSatellite can run on plain LevelDB or SQlite3 world databases but this reduces the performance significantly.

 This is also not tested very well and will likely break your database. So do not use it! Stay with the
 interleaved format!

 Change `-source-backend=sqlite` to `-source-backend=leveldb` if your world is stored as a LevelDB.
 `mtdbconverter` can also be used to convert your world back to the plain key scheme.
