摘要
本文基于目前国产高分辨率卫星影像的发展现状,结合1∶1万基础地理信息数据的特点,研究了一套利用多源卫星影像进行基础地理信息数据快速更新的方法,通过具体研究试验,对生产各环节关键技术进行了深入探讨及反复试验。经实际生产论证,该方法在保证成果质量能够满足规范要求的前提下,有效节约了经济成本,提高了生产效率。
Based on the current development status of domestic high-resolution satellite imagery,combined with the characteristics of 1∶1 million basic geographic information data,this paper studies a set of methods for rapid updating of basic geographic information data using multi-source satellite imagery.The key technologies in all aspects of production have been thoroughly explored and tested repeatedly.According to the actual production demonstration,this method effectively saves economic costs and improves production efficiency under the premise of ensuring that the quality of the results can meet the requirements of the specifications.
