Methods and Research of Obtaining Geographic Information Resources Based on OSM Data

老挝是参与“一带一路”建设最积极的国家之一,了解老挝的地形地貌、地理环境和相关自然信息,将为实施“一带一路”国家战略提供基本条件。本文选取老挝的首都万象为试验区,以1∶10000地形图为试验范围,采用以平面采集为主,立体采集辅助的方式采集地物,对于属性判读采取内业综合判读和参考相关资料相结合的方式,完成地形要素数据和数字线划图,为掌握国外的地理信息资源提供一种有效的研究手段。

Laos is one of the most active countries in"The Belt and Road".Understand the topography,geographical environment and related natural information of Laos,will provide basic conditions for the implementation of"The Belt and Road"nation strategy.The paper got 1∶10000 topographic data and digital line graphic in Vientiane.The drawing of object is based on DOM mainly and three-dimensional acquisition auxiliary.And the interpretation of attribution is by the way of combining artificial means with relevant data.It will provide an effective means of obtaining geographic information resources in countries.
