Innovation documentation procedures are very necessary for the protection of cultural heritage sites in general. This study investigates the capabilities of 3D laser scanning and drone photogrammetry in saving accurate documenting and preserving the delicate features of architectural history. The objective of the study is to establish a definitive plan for choosing the optimal technology, either 3D laser scanning or drone photogrammetry, based on the specific needs and status of a restoration project. That's by analysing the benefits and limitations of both technology and investigate the potential for integrating them together. As this research aims to determine the most suitable applications for each approach by evaluating their performance in terms of accuracy, resolution, data acquisition speed, and adaptation to varied environmental conditions. The results demonstrate that 3D laser scanning is highly effective in collecting intricate features, whereas drone photogrammetry provides quick coverage of large areas. The study's findings indicate that employing a combined strategy can greatly increase the quality and efficiency of architectural documentation. This, accordingly, leads to enhanced preservation efforts and deeper comprehension of cultural assets.
