7月2日,由南京市规划局组织编写的《南京市大比例尺地形图数据标准》(2014版)专家评审会在南京召开,来自北京、上海、安徽、南京等地的业内知名专家参加本次评审。
与会专家一致认为,《南京市大比例尺地形图数据标准》(2014版)制定的需求分析充分、目标定位准确、内容全面具有可操作性。标准结合南京的具体情况,规范了基于CGCS2000坐标系统的新的南京市测量基准,实现了基础地理数据制图、建库与应用一体化,实现了从图幅管理到单元管理的跨越。有助于提高数据生产、管理与应用水平,数据标准达到了国内领先水平。
《南京市大比例尺地形图数据标准》(2014版)颁布实施是南京市测绘行政主管部门部署落实国家测绘地理信息局《关于加快2000国家大地坐标系推广使用的通知》的重要举措,是南京全面启用2000国家大地坐标系的重要保障。
In July 2nd, written by Nanjing City Planning Bureau organizations "Nanjing large scale topographic map data standard" (2014 Edition) the expert review will be held in Nanjing, the famous experts from Beijing, Shanghai, Anhui, Nanjing and other places to participate in the review.
The experts agreed that, "large scale topographic map data standard of Nanjing city" (2014 Edition) requirements analysis for full, accurate positioning, targetcomprehensive operational. Standard combined with the specific circumstances of Nanjing, regulate the Nanjing benchmark new CGCS2000 coordinate system based on the realization of the basic geographic data, graphics, database and applicationintegration, realizes from map management to the unit management across. Help to improve the production, management and application level data, data standard has reached the leading domestic level.
"Large scale topographic map data standard of Nanjing city" (2014 Edition) is the promulgation and implementation of administrative departments of Surveying and mapping of Nanjing implementation of the deployment of the State Bureau ofSurveying and mapping geographic information "about accelerating" ImportantNotice 2000 national geodetic coordinate system to promote the use of, is an important guarantee for Nanjing to fully enable national geodetic coordinate system 2000. |
