    Capturing the Past: Photogrammetry for Safeguarding Sudanese Cultural Heritage Digitally
    (INFORMATIK 2024, 2024) Abdalhaleem, Duaa; Elkhalifa, Akram A.
    Cultural heritage is a valuable asset for any country, and it is crucial to protect, restore, and preserve it because it is threatened by both nature and human actions. Preservation methods have always been a significant concern, and traditional methods of documentation, such as 2D drawings, pictures, and conventional 3D modelling systems, have proven to be inefficient in terms of cost, time, effort, and quality. However, with advancements in technology and digital transformation, more effective techniques have been developed. One such technique is photogrammetry, which has proven to be a convenient way to digitize cultural heritage. For countries such as Sudan, where rich inheritance is in inevitable danger of ongoing armed conflicts, it is important to preserve this cultural heritage. This paper studies the feasibility of using photogrammetry as a digitalization technique to preserve Sudan’s cultural heritage by reviewing previous experiences and conducting two case studies that investigate the applicability of the technique to non-experts, along with its potential and limitations. Selected objects were digitized using close-range photogrammetry with a low budget and simple equipment. The final outcome was promising, particularly for small and medium-sized objects. Finally, a list of recommendations is provided to facilitate the digitalization of Sudanese cultural heritage to preserve it.

    Digital Transformation Of Cultural Heritage In Sudan: An attempt to save a nation’s history, the case study of old Dongola and Al-Khandag, Sudan
    (INFORMATIK 2024, 2024) Khalifa, Alaa; Alhaj, Lina
    Sudan has a lengthy past that dates back to thousands of years before the birth of Christ. In the city of Merowe alone, there are more than 200 pyramids, more than there are in all of Egypt. There have been several experiments and initiatives aimed at digitizing Sudan’s cultural legacy, but the majority of them focused on folklore; little attempt has been made to preserve the physical cultural heritage. The paper discusses the status of Sudan’s historic sites and the outcomes of previous digital conservation efforts. It addresses these issues within the context of digital conservation trails of physical monuments using photogrammetry, highlighting the urgent problem posed by the nation’s on-going civil war and its impact on conservation trials. Utilizing photogrammetry scanning software Metashape, the sites of Old Dongola and Al-Khandag were selected for conservation trials. This approach enabled the creation of digital models of the monuments, ensuring their accessibility in the event of conflict or potential deterioration.

    Digitization of cultural heritage using photogrammetry: The case of Al Bidya Mosque
    (INFORMATIK 2024, 2024) Abdalhaleem, Duaa; Abdelrahman, Duaa; Ahmed, Mohamedalmugtaba; Ahmed, Zainab
    Cultural heritage of a nation forms its identity, inherited from past generations and to be passed to the next. Therefore, it is crucial to preserve it from natural and human effects or even worse, extinction. Throughout time, several approaches were utilized to preserve the cultural heritage from text, drawing, photographs to the modern-day digitized 3D models, points clouds with coordinates, achieving a higher accuracy and more realistic results. This paper focuses on the digitization of cultural heritage using close range terrestrial photogrammetry. The study was conducted on a self-financed low budget, simple equipment and non-professional group of researchers. Al Bidya Mosque, the oldest mosque in the United Arab Emirates, was taken as a focal point of the study, reflecting the country’s cultural and religious heritage built in the 15th Century. The main objective of this study is to investigate how cultural heritage sites can be documented and preserved using close range photogrammetry while exploring the potentials and challenges of close-range photogrammetry.

    Photogrammetric Analysis for Accurate Three-Dimensional Reconstruction of the Mudhafaria Minaret in Erbil (Kurdistan Region of Iraq)
    (INFORMATIK 2024, 2024) Mustafa, Sima; Qader, Aland
    This paper presents a photogrammetry-based approach for the digital reconstruction of the Mudhafaria Minaret in Erbil, Kurdistan Region of Iraq. Hundreds of two-dimensional images were transformed into a detailed three-dimensional model of the minaret using photogrammetric methods and software. The photographs were captured from various perspectives, making sure that all angles of the minaret were documented. The data were then uploaded onto specialized software that generated a detailed 3D model. The employment of three-dimensional scanning makes it possible to conserve cultural assets and accurately chronicle historical events with greater ease. Through the use of digital reconstruction, we are able to acquire a more in-depth comprehension of our shared history, as well as a deeper respect for it. In order to achieve this goal, it’s necessary for us to demonstrate that photogrammetry is not only dependable but also flexible for use in the field of cultural heritage.
