1、Ⅰ、DEM生成实习:1.Sarscape,basic,importdata,standarformat。2.对两个时期的影像进行数据转换:第一栏改为ers1-ers2;输入leadfile,datafile,输出路径,start。3.Sarscape—basic—multilooking,打开两个上一步转换后的.slc,转换成.pwr。4.在19930129.pwr显示窗口双击裁剪。5.裁剪:sarscape—tools—sampleselections—manualselection—iuput19930129.slc西:2600;东:3600;北:12
2、400;南:18400;Start生成一个slc-rsp文件。对裁剪后的进行multilooking6导入dem数据。Basic,importdata,tiff,输入dem,catagraphic,commit,start。7sarscape,interferometry,baselineestimate,masterfile:0129.slc。rsp;slavefile:0305.slcStart,8.相位解缠sarscape,interfermotry,inferogramtophaseunwrapping,输入inputmasterfile:1993
3、0129.slc.rsp;Slavefile:19930305.slc;dem:19930129dem;阈值从0.25改为0.1生成19930129.upha。9vector;createnewvectorlayer;usingrasteimagefile;在弹出窗口open199930129.cc,ok在窗口改layer名为gcp,将gcpload到cc上,Mode,addnewvectors,point在cc窗口双击选点,选相关值大于0.6,10个点左右。.选完后,右键acceptmultipoint。sarscape;tools;generategc
