| 摘 要： | 为了促进小卫星数据在地质灾害监测中的应用与推广,本文以监测采矿图斑变化为目标,通过对北京地区的2006年和2007年两期北京一号小卫星4m全色影像采用正射校正、配准和迭加对比的方法发现变化信息。结合1∶50 000影像图、野外调查和测量,确定变化图斑的边界、变化原因和规模,并对小卫星全色图像的变化监测能力进行分析和总结。本文通过对小卫星4m全色影像数据的分析,基本上可以概括出其变化监测能力。

| Abstract: | In order to impose the application and popularization of small satellite data in the monitoring of geological disasters,this paper,with monitoring changes in mining plans as the target,using two 4m panchromatic images of Beijing-1 in Beijing area in 2006 and 2007,studied the change information through geometry correction,registration,superposition and contrasted.With images of 1∶50 000,field investigations and measurements,it determined the variation of the spot boundaries and the reasons for changes in size,at the same time it analyzed and summaried the ability of small satellites image in monitoring.This paper can sum upits monitoring capacity generally by analyzing small satellite data. |
