【摘要】 目前我国1:10 000基础地理信息的覆盖范围偏低、更新周期偏长、现势性较为陈旧。本文拟从基于GF-7卫星数据的典型矢量要素快速提取、制图综合、智能出图等方面开展研究,突破1:10 000快速测图和更新关键技术难题,研发相应的生产软件系统,提升我国1:10 000基础地理信息资源建设能力。更多还原

【Abstract】 The current coverage of 1:10 000 fundamental geographic information in China is insufficient and outdated.This paper intends to carry out research on the realm of information extraction of typical vector elements based on GF-7 satellite data,cartographical generalization,and intelligent map making.The program will make break through on the key technical problems of the production of 1:10 000 fundamental geographic information mapping,and develop a corresponding production software system.This will enhance the Chinese 1:10 000 fundamental geographic information resource construction capabilities.更多还原
