The topographic survey 
The topographic scheme is a close polygonal and the 
vertices are the station points used for the detailed survey. 
Employing an electronic theodolite Wild TC 2000 
including an infrared distantiometer we determined the 
plano-aitimetric coordinates of more than 800 points, 
with a rather good distribution that is to say homogenous 
and useful for a significative representation. 
The following figure concerns a large scale elaborate ( 
1:1000 ) with contour lines of 1 meter obtained by the 
interpolation of the 800 detailed points: it means certainly 
a good altimétrie description of the ancient place. 
Besides we can observe the detailed planimetrical 
representation locality (fig. 7): the correct localization of 
the Kastro and the ruins of the most important fencing 
walls. 
With regards to the important archaeological aspect of 
the walls it's to observe that the planimetrical information 
of this figure will be completed earning out a terrestrial 
photogrammetnc survey as we can sec soon.

The photogrammetnc survey of the walls 
The walls we can see in figures n c 1-2 and 3-4 have been 
the object of the terrestrial photogrammetnc survey 
performed out using different methods. 
Beginning with the employed instruments for taking the 
photogramms. we can mention the metric camera Wild P 
31, focal lenght 100 mm ( more exatly 99.48 mm ) and 
photogramms size 9 x 12 cm 2 . 
Besides, during this operative phase we used the 
semimetric camera Rollev 6006. focal lenght 40 mm and 
photogramms square size of 6 cm. 
With reference to a first wail example we observe that all 
the control points useful for the absolute model 
orientation have been before signalized with apposite thin 
sticked cardboards. 
The three coordinates of these points have been 
determined following the topographic scheme of the 
forward intersection and using, of course, the same 
instrument mentioned before (TC 2000 ). 
The traditional restitution of the wall n° 4 was performed 
employing the analythical plotter Galileo Digicart 40. 
The graphical elaborate on a rather high representation 
scale 1 : 20 is certainly very good for what it concerns 
metrical considerations. 
It's possible to observe also the graphical elaborate 
carried out taking care of the contour lines (each every 2 
cm).

This complete and accuracy three-dimensional 
representation is not yet satisfactory enough for the 
descriptive aspects, that is to say. for example, the 
conservation situation of the wall. 
These last information are instead included in a further 
elaborate ( of course at the same scale 1:20) obtained by 
restitution with only one photogramm. using the 
rectification method. 
The employed instrument in this case, was the Zeiss 
SEG VI and the result of this work appears in the next 
figure 9. 
The two different methods ( classical model restitution 
and rectification of only one photogram ) give a very’ 
good opportunity to investigate the archeological walls. 
In fact both the aspects: the geometrical and the 
descriptive one are very well safeguarded
