Abstract. In this paper an alternative method for measuring the Classic Marathon Course using photogrammetric methodology is presented and examined. The course is surveyed in stereoscopic environment and therefore the measurement is performed directly in 3D space. The produced elevation data after the processing procedure are presented in the section plan at a scale of 1:5.000. The Digital Surface Model, with a step of 5m, and the orthophotomap at a scale 1:2.000 of a corridor area, with width of 100m on either side of the course represents an additional product of the photogrammetric method. At the end, in this thesis the photogrammetric methodology is being assessed and evaluated, but also it is being compared with the conventional method of the calibrated bicycle and finally are conclusions drawn and proposals are attempted.
