西藏建筑遗产测绘中的技术适用性

Usability of Architectural Heritage Surveying Technologies in Tibet

建筑遗产测绘为建筑史研究提供史料、为建筑遗产保护采集数据,其重要性自不待言。然而,测绘技术的适用性在我国还没有引起广泛重视。比如,由于独特的地理环境和建筑类型,西藏建筑遗产测绘中并不能照搬华北地区常用的激光扫描和CAD二维绘图。该文介绍了西藏建筑遗产的特殊性及其对测绘技术的影响,并通过江孜白居寺和年楚河流域的建筑遗产两组实例对测绘技术进行了对比,结论是低空摄影测量和GIS在西藏的建筑遗产测绘中具有广阔的应用前景。

Architectural heritage surveying is the foundation of architectural history research and heritage conservation. However, the usability of surveying technologies is often neglected in China. The surveying technologies for North China, terrestrial laser scanning and CAD- based 2D drawing, are constrained in Tibet due to unique terrain and architectural typology. In this paper we illustrate the characteristics of Tibetan architectural heritage and its influence on surveying technologies. Comparisons are carried out between different surveying technologies with the case studies of Baiju Temple and architectural heritage in the Nianchu River basin. The conclusions that low-altitude photogrammetry and GIS are promising surveying technologies in Tibet.
