北京市1:50000地形图缩编更新生产工艺设计

结合北京市地理数据现状,在对现有数据和国家1:50000地形图缩编要求综合分析基础上,设计了利用1:10000DLG缩编更新北京市1:50000地形图的生产工艺.该工艺不仅有效的利用了现有的正射影像和矢量资料,而且将搜集到的民政勘界、交通专题数据有机地运用到1:50000地形图缩编更新中去,较好地满足了国家1:50000地形图缩编更新的要求.实践证明,本文设计的缩编工艺是可行的,对其他单位和部门的1:50000地形图缩编生产具有一定的参考价值.

The Production Technology of 1:50000 Map Compilation Update in Beijing

This paper considers the status of Beijing's geography data and basing on the analysis to the data and the requirement to 1:50000 map compilation of national bureau of surveying and mapping,designs the production technology of 1:50000 map compilation update using 1:10000 map.The technology uses not only DOM and vector data in existence,but also the civil administration survey boundary and traffic special data in compilation,meets the requirement to 1:50000 map compilation of national bureau of surveying and mapping.Practise proves out that the map compilation technology this paper puts forward is realizable,and has reference value for other institute or branch in 1:50000 map compilation update.
