全球测图项目中基于不同软件进行DSM匹配结果的探究

10 m格网数字表面模型(DSM)是全球地理信息资源建设与维护更新(简称“全球测图”)项目中的一项产品,它是基于资源三号卫星立体影像及RPC参数,利用DSM生产软件,针对不同地形进行DSM匹配,进而进行DSM产品的生产。本文以全球测图项目为背景,探究利用Inpho7.0、PixelGrid6.0、CIPS 3种主流生产软件进行DSM匹配,探究不同软件在匹配精度、匹配效果和匹配效率方面的差别,得到不同软件在DSM生产中的使用原则,不仅为DSM产品的生产提供了技术支撑,也为全球测图项目的顺利推进提供借鉴和经验。

Exploration of DSM Matching Results Based on Different Software in the Global Mapping Project

10 meters′grid network digital surface model(DSM)is a product of the project named global geographic information resources construction and maintenance updates(hereinafter referred to as the"world map"),it is based on three resources satellite stereo images and the RPC parameters,using DSM production software,according to different terrain DSM matching,then the DSM products.Based on the global map project as the background,this paper explore the use of three mainstream production software DSM matching including Inpho 7.0,PixelGrid 6.0 and CIPS,to explore the different software in matching accuracy,match the difference of efficiency,effect and get a different software used in the production of DSM principle,not only provided the technical support for DSM products,also for the global mapping project smoothly to provide reference and experience.
