摘要
我国首颗亚米级立体测绘卫星,高分七号在1∶1万基础地理信息数据更新具有精度高、成本低、覆盖广、更新快等优势,本文结合1∶1万基础地理信息更新的业务标准与规范,探索了基于高分七号立体测绘数据开展1∶1万基础地理信息更新的技术流程与方法,验证其在1∶1万基础地理信息数据更新中的测图精度和适应性。结果表明,利用高分七号立体测绘数据开展1∶1万基础地理信息更新,其测图精度较高,可作为省级1∶1万基础地理信息资源数据更新应用数据源推广使用。
As my country's first sub-meter-level stereo mapping satellite,Gaofen-7 has the advantages of high accuracy,low cost,wide coverage,and fast update in the 1∶10000 basic geographic information data update.This paper combines the 1∶10000 basic geographic information update,it explores the technical process and method of 1∶10000 basic geographic information update based on Gaofen-7 stereo mapping data,and verifies its mapping accuracy and adaptability in the 1∶10000 basic geographic information data update.sex.The results show that the 1∶10000 basic geographic information update using the Gaofen-7 stereo mapping data has high mapping accuracy and can be used as a provincial 1∶10000 basic geographic information resource data update application data source.
