Abstract Old maps are powerful tool in providing valuable information about the landscape. Traditionally, hard copies of old maps are stored in archives. The Internet, particularly Internet application and servers, have changed the way cartography works. Old maps can now be viewed on the Internet, can be compared with other maps or be distributed to other web map servers. Particularly the wide distribution of old maps on the Internet is the step into the future, when maps will be easily accessed and widely used. Typical users of old maps are environmentalists, historians and general public.
