一观测员将经纬仪安置在测站A点上(已知HA=26.432m)量得仪器高i=1.45m,盘左时望远镜对准立在B点上的地形尺三丝读数分别是1.680m,1.180m,0.680m,竖盘读数为84°06′,(若X=0)试求:DAB,hAB和HB()A、DAB=99.94m,hAB=10.56m和HB=38.992mB、DAB=98.94m,hAB=13.56m和HB=37.992mC、DAB=98.94m,hAB=10.56m和HB=36.992mD、DAB=99.94m,hAB=13.56m和HB=37.992m
已知道Ha=100.000m,ab测段往测高差⊿hab= -0.010m,返测高差⊿hba=-0.006m,则Hb高程为()。A、99.998mB、99.992mC、99.996mD、100.004m
单选题已知AB点绝对高程是HA=13.000m,HB=14.000m,则hAB和hBA各是()。A1.000m,-1.000mB-1.000m,1.000mC1.000m,1.000mD-1.000m,-1.000m
单选题A、B两点,HA为115.032m,HB为114.729m,则hAB为()。A-0.303B0.303C29.761D-29.761
