Aims and Endeavors
The purpose and dedication of the creators of the archive
The basic aim of aerial image collection, digitization, andsystematizationinto single database is the qualitative archiving of photographs ensuring maximum data extraction. Formerly the photos were often digitized in low resolution because of practical image storing, and,unfortunately,many original photographs were destroyed or scrapped. In our publishing activities, we endeavoured to help in finding the appropriate procedures for the different materials.After the initial negotiations with museums, major photo archives and private collections, it was agreed to organize the digital Archive for long-term preservation of images.We aimed to create a laboratory and data recording method operating under strict standards based on a non-profit project, which started in 2007. The professionals from photogrammetry and aerial survey organizations knowing the circumstances and the customers of images helped to seek the collections preserved in various condition and quality.Concurrently with the digitization, the database's setting up and the images' continuous systematization was conducted.Our other aim is to pursue preserving and collecting further archival images and maintaining the Archive. To provide financial background for this, the images are purchasable in the webshop. The Archive’s collection is composed of part-collections of several museums and collectors. Although the digitization was carried out by the Interspect Group, the digitized part-collections have joint licensing based on the preservation andthe ownership of photographs.In these cases the original archive and the digital archiving team shares the revenue. The Interspect Group spends its income of the revenue entirely to expand and maintain the Archive.
The original photographs are in varying conditions; accordingly they are classified into different categories:
- Intact: The entire surface of the photograph is intact, there is no irretrievable damage, and the photo is sharp and well-exposed
- Surface damage: The surface of the photograph is damaged, stained or worn
- Defective: A part of the photo is torn, broken and lost
- Broken: The photograph is torn or broken but the entire surface can be reconstructed
- Blurred: The focal length was incorrect or the camera was blurred or shaky
- Light: The photo is overexposed
- Dark: The photo is underexposed
Camera axis:The vertical axis images were taken with acamera on the board facing approximately perpendicularly downward. It is mainly used for cartographic, remote sensing and Earth observation purposes. The perspectiveaerial images were taken with oblique camera axis showing the landscape slantwise. The Archive contains a number offield images too, in different aviation, technical and scientific subjects.
The spectrum of images expressesin which range of electromagnetic waves of film or digital image sensor was the photo taken.
