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.

This research aims to explore the potential of low cost video camera for 3D modelling of large historical monuments. As we know, photos extraction is a fundamental issue in any photogrammetric project. In fact, cost and time are dependent on photo extraction method. Usually, photos are taken one by one assuring that every object point is on two photos at least. This operation is time consuming in large scenes modelling. In the other hand, video record is a simple operation and requires short time comparing to traditional photo shooting. Then, it will be useful to suggest an approach to use video recordings as a source of photos required for 3D modelling. In the present study, we will evaluate the capability of two video cameras. The first one is a commercial independent camera and the second is associated with a mobile phone in the extraction of photos required for 3D modelling of a relatively large objects. It should be noted that the resolution of video frames in mobile phone cameras (comparing to professional ones) is less than the resolution of ordinary photos. Hence, 3D models resulting using these frames will be good for applications that don’t require high precision.
3D models of historical sites and monuments are very interesting in archaeology and digital tourism fields. These models help archeologists document historical sites and analyze the relationships between their components. Moreover, 3D models constitu te an attractive factor that encourages visiting sites and presents virtual information about cultural heritage. In this paper, we propose an approach that uses capabilities of CAD (Computer Aided Design) and GIS (Geographic Information System) systems to construct spatial and semantic database for historical sites and modeling them in 3D. Users of the mentioned database can use it to gather information about sites and to navigate across them via the animation capabilities in GIS. The proposed ideas will be applied on the historical site of Ras-SHAMRA in Lattakia. Spatial data concerning the site will be acquired form a topographic plan designed in 2004. These data will then be processed and introduced into GIS environment. ArcGIS software will be used to achieve an Archeological Information System (AIS) for the site and to construct a 3D model of the site and the royal palace.
The importance of research lies in the need to keep pace with the technological development of computer systems and technologies Modern methods, especially geographic information systems, in collecting, storing, analyzing and exiting Spatial inform ation and linking it to metadata, modeling and scenarios Planners and decision-makers to assist them in planning and finding appropriate solutions for various problems.
This research highlights the vital role of Pavement Management Systems integrated with Geographic Information Systems in planning and managing road maintenance in Lattakia, and getting a flexible local system by following a new method in processing a nd viewing information that supports maintenance decision. This study included applying a pilot project for managing pavement maintenance over a group of roads following The General Establishment for Road Communications. Those roads were divided to links and segments then evaluated using the " Asphalt Institute Method ", which gave us a numeric pointer that led in turn to the type of maintenance needed for a particular pavement. In this research, we depended on the Geographic Information Systems to design and build a comprehensive database, that reflected the present condition of the studied roads, and enabled us to store, analyze and document pavement surface condition and link it to the digitized maps of the studied roads. This guaranteed easy and direct access to various kinds of data and solutions as every segment appeared in a different color reflecting its conditions according to the theme of the map. By doing so, we could support the process of taking right maintenance decisions.
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 mus t 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.
