基于新型基础测绘的西宁市地理实体数据规范研究与验证

Research and verification of geographic entity data specification in Xining based on new basic surveying and mapping

为了更好地推动西宁市新型基础测绘数据的管理和共享,解决传统测绘在产品形式、技术方法、管理方式等方面日益凸显出来的问题,本研究紧紧围绕国家新型基础测绘建设总体要求,将原有以“地理要素”为视角和对象、按“比例尺”构建的基础地理信息数据,转变为以“地理实体”为视角和对象、按“实体粒度和空间精度”构建的地理实体数据,积极探索研究,对地理实体的分类、实测内容、空间身份编码和数据组织进行规范,更好地为西宁市地理实体数据的采集、处理、建库和应用服务提供支撑。

In order to better promote the management and sharing of new basic surveying and mapping data in Xining and solve the increasingly prominent problems of traditional surveying and mapping in product forms,technical methods,management methods,and other aspects,this paper closely focused on the overall requirements of national new basic surveying and mapping construction.The paper transformed the original basic geographic information data constructed on a scale with"geographical elements"as the perspective and object into the geographic entity data constructed according to"entity granularity and spatial accuracy"with"geographic entity"as the perspective and object.It actively explored and carried out research to standardize the classification,measured content,spatial identity coding,and data organization of geographic entities,so as to better support the collection,processing,database construction,and application services of geographic entity data in Xining.
