Hi Tom,

thanks for your fast reply. ;)

I'm not sure if I got the point: instead of saving the lat/lon-values to 
my db and calculate the coordinates on demand, I should rather convert 
the values into a plane-projection like the slippy map does and then 
create my tiles and search index based on it?

Or did I completely miss the point?
