摘要
实景三维自提出以来,不断探索新模式新方法并取得了显著成效。然而由于建模方法和软件工具多样,不同地区基础地理实体数据格式、数据标准并不完全兼容,统一高效的存储格式标准还是空白,严重阻滞了数据在不同区域不同行业间的共享流通。本文以畅通不同格式、不同类型数据交互为重点,梳理分析当前用于存储地理实体数据模型现状,以当前地理实体数据交换格式标准为基础,研究统一、通用、开放的地理实体数据存储与交换模型,并结合实际生产数据进行探索试验,验证了本文方法的可行性,为形成可供广泛交流和共享的标准规范,促进实景三维数据的应用和推广提供参考。
Since the concept of realistic geospatial scenes in China was brought forward,extensive research and exploration have achieved remarkable results.However,the abundance of modeling methods and software available has led to inconsistencies in fundamental geo-entity data formats and data storage standards across different regions,impeding lossless data conversion.A unified and efficient data storage format standard is necessary to circulate and use data between different regions and industries.This paper designs a unified,general,and open geographic entity data storage and exchange model based on an analysis of the current status of geographic entity data storage models.By taking real geo entity data as an example,the paper verifies the feasibility of the model.This research could provide a reference for forming a widely communicated and shared standard specification,thereby promoting the application and dissemination of real-world 3D data.
