Reviewer comments

I found that the link supplied here at first doesn't qualify as the data we are looking for, but, the THE HELLENIC MILITARY GEOGRAPHICAL SERVICE (HMGS) offers an e-shop for maps and data which seem to cover our needs, since I could not varify the data itself many questions are left unsure, however I am positive the data exists, even digitaly, and open to the public for a price, and some of it is online to view but not to save. link to the e-shop:,46034&_dad=portal&_schema=PORTAL link to the viewer:
