This study investigates the digitization of a cooling tower at the SPS (Steam Power Station) Kardia plant in Ptolemaida, Kozani, Western Macedonia, aiming to provide practical insights into digitization methods for cultural and industrial heritage structures, focusing on photogrammetry to bridge traditional conservation with modern digital technologies for sustainable preservation. The study consists of two main parts. The first involves a comprehensive literature review on cultural heritage conservation, digitization methodologies, and digital documentation techniques, emphasizing the information modeling of historic buildings and highlighting exemplary projects. Additionally, 48 studies are analyzed and categorized based on scale, digitization goals, and documentation methods for comparative analysis. The second part focuses on the experimental digitization of the cooling tower, examining two experiments conducted in 2023 and 2021. These experiments address practical challenges in the digitization process, with findings scrutinized to discuss their broader implications. This study offers practical knowledge on applying photogrammetric methods in heritage digitization, providing valuable guidance to stakeholders in conservation and digitization. The goal is to ensure the sustainable preservation and potential reuse of cultural and industrial heritage for future generations.
