Photo Interpretations

The interpretation of photos is a very important and scientifically accepted method for the study of properties’ boundaries as well as the finding of their possible changes at a specific time. Their photo interpretation is useful for ascertaining the land use at a specific place and for the calculation of any changes from a specific moment in the past until today. This is accomplished either with single images observation or with stereoscopic observation and processing of stereo-pairs.
During an image observation for the outcome of conclusions, differentiations in shapes and sizes of depicted objects are examined as well as differentiations in tone and texture of the image. During the observation of a stereo-pair, the subject of interest is examined as it is in reality since 3D observation and images enlargement are achieved. In addition, complex technical cases can be dealt like dimensioning of objects in space, not only from stereo pairs but also from single oblique image of previous years.
For the total of Greek area, the HGMS, the NCMA S.A., the Ministry of Rural Development and private organizations have a rich, historical archive of aerial images, which covers series of aerial photography in different scales and resolutions. The archive can be exploited in land use studies, characterization of forested areas, monitoring of residential development, arbitrary building location, and documentation of older regimes, river flow changes, coastlines and in many other applications.
Modern technology of digital photogrammetry gives actual measuring results with impressive accuracies using as primary data, historical data even from amateur photos of the previous century.
Map International has successfully completed a large number of these projects. A company’s study has presented in the Council of State in a legal case and technical report of Map International was accepted by the Directorate for the Restoration of Monuments and Conduction o Technical Works of the Ministry of Culture.
