Abstract

The recent development of camera sensors, the manufacturing of lenses and the accurate algorithms of photogrammetric software allow today to acquire point clouds similar to those generated from a laser scanner. The results are similar: numerical models that contain a variety of information, useful for the final data synthesis. Thanks to the automatic points recognition of photogrammetric algorithms, it is now possible to revise part of digital data previously acquired and use them in new computing strategies. Emblematic is the example of the crusader castle of Wu'Ayra, an important medieval fortress located in the Petra valley in Jordan. Since 2000, in collaboration with the international mission of the University of Florence, a number of surveys aimed at detecting the whole monumental area, the archaeological site, the settlement and the defensive system of the castle were performed by the research team of the Italian ITABC-CNR. Different survey techniques were used during the acquisition step, in order to enhance the main information of the archaeological site and the geomorphology of an extended area particularly complex to be defined. In these 15 years, the team tested several techniques. Thanks to recent software, the team has revised old data, created a defined numerical model of Wu'Ayra, updated and improved the documentation. The Authors illustrate the results of these elaborations and compare them with the other systems used, highlighting the differences and updating the graphic documentation of an important site in the history of the Petra valley. Furthermore, latest data of the architectural structures of the formworks acquired with laser scanner will be presented.
