摘要
为更好地满足国民经济社会发展和生态文明建设、国防建设以及自然资源管理对地理信息更新服务日益提高的需要,多年来,国家基础测绘不断提升数据的丰富性、现势性以及可靠性,建立完善的适用于我国国情的基础地理信息更新技术与业务体系,管理体制与运行机制,实现了一年更新一次。本文主要针对国家基础测绘1∶50000地形数据更新的技术路线及流程、生产方法进行了总结和思考,并提出了今后如何开展的思路及建议,以期为1∶50000地形数据更新下一步的工作开展提供借鉴。
In order to better meet the increasing needs of geographic information updating services for national economic and social development,ecological civilization construction,national defense construction and natural resources management,for many years,the national basic surveying and mapping has continuously improved the richness,current situation and reliability of the data,and established a perfect basic geographic information updating technology and business system,management system and operating mechanism,which are suitable for the national conditions of our country,and have achieved annual updates.This paper puts forward some ideas and ideas in the aspects of the technical route,process and production method of 1∶50000 terrain database updating,and gives some ideas and suggestions about how to carry out it in the future.It is expected to provide reference for the next step of 1∶50000 terrain database updating.
