The whole area of study is included in the air photographs of 1953, 1962, 1970, 
1979. These photographs have been used as a basis for the diachronic monitoring 
of the area. The remaining photographs have been used supportively, because: 
i) they do not include the whole area (1932, 1959) and ii) their scale is small 
(1937,1967). The basic cartographic support of this study were the topographic 
ir diagrams of 1:5.000 scale. The map sheets of the town plan have been used in 
order to determine the boundaries of the parts of the area that have been in- 
cluded in the town plan during the years 1938 and 1968-69. 
Then, using the remote sensing methodology we created the land use maps for the 
four periods (1953,1962, 1970, 1979)* 
To test the reliability of the remote sensing conclusions, we did 30 fieldtests 
in random positions. The small scale of the air photographs, in addition to the 
S known problems that the photointerpreter faces in urban areas, and the fact that 
we did not use orthophotographs, do not permit the drawing of reliable measuring 
conclusions. 
The different land uses have been measured on the land use maps, and the perce- 
fic ntage distribution of land uses at the area where these are related (total area 
h of study, part of the area that was included in the town plan in 1938, and part 
it included during 1968-69) have been determined. 
C- Using the air photographs of the first periods.the following land use classifi- 
cation has been determined: 
phs 1. cultivated land 
ler 2. country houses 
3. transportation network 
a For the land use classification of the following years, the categories below 
= have been distinguished: 
1. residential area 
two 1.1. single-family residence 
n 1.1.1. scattered residence 
1.1.2. dense 
S 1.1.3. country houses 
tres 1.2. multi - family residence 
2. working area 
rt 2.1. open working space (parkings, car deal lots e.t.c.) 
n 2.2 closed ™ " (industry, handicrafts e.t.c.)
