新型测绘一体化技术在基础数据调查中的应用——以广州市大源整村改造为例

Application of New Surveying Integrative Technologies in Urban Basic Geoinformation Investigation

基础数据调查是城市更新工作的重要部分,也是科学制定改造方案,进行项目经济测算的重要基础依据。本文以大源村基础数据调查项目为例,针对目前基础数据调查工作中的难点,设计了一套从外业数据采集到内业数据处理、管理、分析的基础数据调查一体化方案。基于智慧广州时空信息云平台实现无人机测图、多源数据入库、大数据分析、建立大源村空间信息数据库的全流程作业,探索了新型测绘技术和信息化管理体系在基础数据调查中的应用。

Urban basic surveying and mapping is the one of most important step in urban planning,furthermore influences on scientific design alternative of urban renewal and economy estimation in accordance with investigation results.This paper takes Dayuan basic surveying and mapping project as an example and designs an integrative scenario including data processing,management,analyzing for solving current difficulties on basic surveying and mapping project.This scenario realizes on combination of UAV tilt photogrammetry technology,multisource geoinformation storage,big data analyzing and cloud GIS with Dayuan project and investigates the applications of new surveying and informatic technologies in urban basic surveying and mapping.
