Alternative Solution to Document Large Historical Façades Using GIS to Produce a Digital Images Mosaics

Culture heritage conservation is necessary to produce the initial technical documentation. This one provides plans that help in using the best approaches to protect culture heritage. Images are considered as an important source of data required to achieve this documentation, where they can be used to extract semantic and 2D-3D geometric data. In case of large planimetric objects, we can use the controlled mosaics as source of these data. In the present study, instead of using professional photogrammetric software, we propose an alternative solution to document the large planimetric historical objects. This approach is based on producing a mosaics from a group of digital rectified photos by using some capabilities of a GIS that are originally applied to produce mosaics from overlapped maps. The produced mosaic well then be used as semantic and geometric documentation source in this GIS. Geographic Information System facilitates largely the conservation, development and renovation process of historical areas. To ensure the validity of the resulted mosaics, we will compare it with a mosaics calculated from the same photos by using a professional photogrammetric software.

Documentation of Historic Monuments Using Multi-Images 3D Modelling

In close range photogrammetry, the required geometric data for object documentation can be obtained from single photo or stereoscopic pairs of photos. But, the documentation of large historic monuments, the stereo pair is not sufficient. So, we must use many photos to cover the whole object. In this study, a new approach for 3D modeling of historic monuments is presented. This one is the multi-images approach. It takes the complicated geometric nature of object to be documented. This kind of modeling is one of most important applications of close range photogrammetry. In this study the results the multi-images approach is exposed by a practical example concerned a historic façade in Housn Souleman (Safita). We used digital photos obtained by the digital camera Kodak 8MP. This camera has a good geometric resolution suitable for precise documentation works. To achieve the modeling, some well known software for documentation purposes were used.

The Monument "Aspect – Importance – Function and Position as a Symbol and Human Architectural Art"

The research clarifies the aspect of the monument, its position, types and different forms since ancient times till now. It also shows the development of its raw materials, ratio and fitness with the space as well as the variations in its classification standards throughout history. This research also handles the effective role of a monumental work in fixing high values in human memory and developing the architectural social reality and organizing the site and place that it occupies not only making it beautiful. The monument is a long term symbol embodied in the meanings reflected by its artistic forms which are full of human and mental senses. This research approaches the issue of majority ignorance of the importance and value of a monument in our countries. Arabic people have a minor or even no knowledge at all of the statue. Efforts should be made to strengthen the relationship between individuals and monumental works as well as architecture in a way that will bring positive results for both and for our homelands.
