The study area of the project was the Thessaloniki–
Athens rail axis, including the railway stations
in these two cities. The total length of the line
is about 450 km and it comprises the 1/5 of the total
length of the national railway network. During the
first stage of the project, 183 digitized maps at a
scale of 1:5000 and 12 maps at a scale of 1:250,000
were produced for the whole country. The Thessaloniki–
Athens railway axis was also digitized at a
scale of 1:5000, together with the railway network
of the country at a scale of 1:250,000.
