The care of monuments, like government planning, needs precise documentation for the architectural analysis,proposed reconstruction and preservation of historical objects. In the recent past, there have been significantchanges in object documentation technologies Current practice uses laser scanning or virtually fully automatic photogrammetricprocesses, which are used for powerful computing and software In the last century, classical stereophotogrammetrywas used as an exact and precise method completed by single photo photogrammetry for planar objects;however, it is very time consuming in its classical form By the end of the twentieth century, digital technology slowlypushed out classic analogue methods Digital technology entails using new instruments, technology, data storage andmanipulation, and offers new possibilities in automated data processing and for the presentation of the results In 1999,the documentation of the Great Umayyad Mosque in Aleppo, Syria, was conducted After an international tender, alldocumentation was carried out by the Czech firm Geodezie CS in cooperation with the laboratory of photogrammetryof the Czech Technical University (CTU) in Prague CTU was responsible for the photogrammetrical work and dataprocessing, while classical geodesy was undertaken by specialists from Geodézie CS. At the end of the last century,analogue cameras were still being used and digital cameras were just beginning to be used In the Umayyad Mosquedocumentation project, mainly analogue metric cameras were used Captured images were digitised and processed onthe first digital workstations. The original results from 2000 are good, but some of the outputs are now quite obsolete.The content of existing historical materials (measurements, CAD outputs, photographs) therefore provides a uniqueopportunity for future reconstruction This paper refers to existing materials, their evaluation and new processing possibilitieswith modern technologies.
