Elaine, Thanks. I could swear I saw something perl-ish referring to the atlas, oh well. Maybe I'll have to write a module in order to use it. At least this will force me to get GD.pm configured ...
Thanks for the pointers, Geo-Tigerline is more than I want to bite off at the moment, but it could be relevant too. Calle's World could be useful for other researches, worth knowing. -- BIll
