上海市“两图融合”地形数据成果的质量控制

Quality Control of Terrain Data From “Two Map Fusion” in Shanghai

上海“两图融合”地形成果兼顾“两图”的技术指标和内容要素,采用建筑工程竣工驱动进行实时更新,遭遇了作业单位增加,质量要求变高,作业软件变化,测量精度提升和内容要素增多等困难,通过优化完善流程,建立质量反馈和处置机制、组织相关单位多级检查、统一检查方法等措施,最终实现质量控制,成效明显。

The results of“two maps integration”terrain updating takes into account the technical indicators and content elements of“two maps”in shanghai,and the real-time updating is driven by the completion of construction projects.It encounters difficulties such as the increase of operation units,higher quality requirements,changes of operation software,improvement of measurement accuracy and increase of content elements.The quality control is achieved though some measures like optimizing and improving the process,the quality feedback and disposal mechanism,the organization of relevant units multi-level inspection and unifying inspection methods,etc,the effect is obvious.
