先农坛高精度实景三维数据集

本数据集通过北京先农坛和中轴线文物遗址保护相关研究与实景三维技术相结合，能够在数字虚拟环境中对先农坛地区建筑、地面、道路和景观等要素内容的空间位置和风貌特点进行精细复原和清晰展示，可支撑工作区范围内各建筑物的发现、修复、展示、利用以及监测等多方面的研究利用工作，为促进先农坛及周边区域的科学管理，助力中轴线文化遗产保护和核心区控规实施提供空间数据保障和工作示范。

This dataset combines relevant research on the protection of cultural relics and heritage sites at Beijing's Xiannontan Altar and the Central Axis with real-scene 3D technology. It enables precise restoration and clear visualization of the spatial positions and appearance characteristics of various elements including buildings, ground surfaces, roads and landscapes in the Xiannontan area within a digital virtual environment. It supports a wide range of research and application activities such as discovery, restoration, display, utilization and monitoring of all buildings within the working area. It provides spatial data support and work demonstration for promoting scientific management of the Xiannontan Altar and its surrounding regions, facilitating the protection of cultural heritage along the Central Axis and the implementation of the detailed control plan for the core zone.
