Hi Locus
I´m not really sure where to turn or who to ask. Do you know any map software/program that could automatically find the lowest point in a country and when you would like to find the second lowest, third lowest point and so on you could find it ? And on that same coin, a software that could find the highest point, second highest, third highest point etc ?
Would love to hear back from you with any suggestions you might have. 

Best Regards
Anders
