[Therion] Lookup explo-date - avoiding overlying scraps

[Pavel Herich]

Thank You all,

I did try this Bruce, with opacity 0 there is just blank page left.
I agree, this could be done by customising map structure, but there is 
need for this for 88 km long cave system gradually discovered during 120 
years.
I´d like to make a video of discovery progress by each year in 
Demänovské Caves, so it should contain ~100 variations of the overall 
map...

And sorry for spam, my mailing server seemed to not working properly, so 
I thought my e-mails didn´t pass through.

Pavel
