测绘地理信息技术在陕西省文物保护区划中的综合应用

近年来，随着国家对文化遗产的高度重视及城市的快速扩张，文物保护管理规划无法与城市规划对接，不利于文物保护与管理工作的开展。本文以陕西省文物保护区划项目为背景，选取铜川市延昌寺塔保护范围为试验区，对延昌寺塔保护区划进行实测，并结合无人机航测、三维激光扫描、三维地理信息系统等现代测绘地理信息技术手段，探讨综合现代地理信息技术方法在文物"两线"精准划定中的作用与优势。通过本文的研究示范，为提升文物保护规划权威性，提高文物管理水平提供了新思路，其技术方法及手段可以在同类项目中推广应用。

Comprehensive application of surveying and mapping geographic information technology in cultural relic protection division of Shaanxi province

In recent years, with the state's high attention to cultural heritage and the rapid expansion of cities, cultural relics protection and management planning can not be connected with urban planning, which is not conducive to the development of cultural relics protection and management. Based on the project of cultural relic protection division in Shaanxi province, the protection area of Yanchang Temple Pagoda in Tongchuan city is selected as the experimental area. Combined with modern surveying and mapping geographic information technology such as UAV aerial survey, three-dimensional laser scanning and three-dimensional geographic information system, this paper discusses the application of integrated modern geographic information technology in the accurate delimitation of cultural relics "two lines" Use and advantage. Through the research and demonstration of this paper, it provides a new idea for improving the authority of cultural relics protection planning and improving the level of cultural relics management. Its technical methods and means can be popularized and applied in similar projects.
