线性文化遗产是指在拥有特殊文化资源集合的线性或带状区域内的物质和非物质文化遗产族群，往往处于人类的特定目的而形成一条重要的纽带，将一些原本不关联的城镇或村庄串联起来，构成链状的文化遗存状态。秦蜀古道，是对历史上穿越秦岭、巴山，连接关中与四川盆地的多条道路的总称，它是中国最为重要的文化线路之一，属于一种线性文化遗产。由于线性文化遗产具有大尺度、多维度、内容广泛等特点，在线性文化遗产整体展示、文物信息化及规划保护方面难度较大。随着测绘信息化技术的快速发展，空间数据的获取手段越来越先进。而三维GIS将多源数据集成于一体，借助其三维表达、空间管理、空间分析等强大优势，应用于信息化文物、文化遗产保护等领域，在文物数据采集、文物发现、文物保护、文物展示、文物修复、文化传承等方面具有重要意义，有利于促进文物保护及管理的高效化、精细化、科技化。 本文将无人机航摄、倾斜摄影、地面三维激光扫描技术等技术获取的多源数据集成于数据库，基于Skyline设计和开发了秦蜀古道三维地理信息系统，多方位、多角度的展示了秦蜀古道基本概况，开发了遗址信息编辑、成果查询、统计分析等功能模块，有利于科学、形象的管理遗址，直观、准确的了解秦蜀古道现有的生存状态及其发展趋势，为构建科学有效的文化遗产保护体系提供辅助。

Linear cultural heritage refers to groups of material and intangible cultural heritage in linear or zonal areas with special cultural resources.It is often in the specific purpose of human beings,forming an important link between a series of unconnected towns or villages, constitute a chain of cultural relics state. The Ancient Qinshu Roads is one of the most important cultural routes in China and belongs to a kind of linear cultural heritage. It is a general term for the history of crossing Qinling, Bashan, connecting Guanzhong and Sichuan Basin.Because the linear cultural heritage has the characteristics of large scale, multi-dimension and wide content, it is very difficult to display the linear cultural heritage as a whole, and is very difficult for the cultural relic informationization,the planning and protection. With the rapid development of surveying and mapping information technology, the means of obtaining spatial data are more and more advanced. The three-dimensional GIS integrates the multi-source data into one, can be used in the fields of information cultural relics preservation and so on, with its powerful advantages of three-dimensional expression, spatial management and spatial analysis. It can be applied to cultural relics preservation, cultural relics discovery, cultural relics protection, cultural relics repair, cultural heritage and so on,and is very meaningful. It is also conducive to promoting the high efficiency, refinement, technology of cultural relics protection and management in related fields. In this paper, the multi-source data acquired by aerial photography, tilting photography and terrestrial 3D laser scanning technology are integrated into the database. Based on skyline, the 3D geographic information system of The Ancient Qinshu Roads is designed and developed. The system represent the existing state and its development trend of The Ancient Qinshu Roads in multi- Visual and accurate understanding, and provide assistance for the construction of the scientific and effective cultural heritage protection system.
