ABSTRACT
With the acceleration of urbanization, historical and cultural blocks are facing dual challenges of preservation and development. Traditional conservation methods exhibit limitations in information integration and dynamic management. In this context, three-dimensional geographic information modeling offers a novel approach to addressing these issues. This study, set against the backdrop of the preservation of historical and cultural blocks, aims to explore the application potential of 3D geographic information models in cultural heritage conservation. By constructing a high-precision 3D geographic information system that integrates remote sensing, laser scanning, and GIS technologies, this research achieves comprehensive digital documentation of the spatial morphology, architectural structures, and historical environments of the blocks. A typical historical and cultural block was selected as a case study, employing a combined methodology of data collection, modeling analysis, and simulation evaluation to systematically assess the practical effects of the model in heritage monitoring, planning decision-making, and public participation. The results indicate that 3D geographic information models can significantly enhance the scientific rigor and efficiency of block preservation efforts, particularly demonstrating unique advantages in dynamic monitoring and virtual reconstruction. The innovation of this study lies in its first-time integration of multi-source heterogeneous data into a unified platform and the proposal of a protection strategy optimization method based on spatiotemporal analysis, providing a replicable technical fr amework and theoretical support for conservation practices in similar areas. Ultimately, it is concluded that 3D geographic information models not only contribute to the precise preservation of cultural heritage but also facilitate the dissemination and sharing of cultural values, holding significant academic implications and application value.
