控制测量工作流程技术设计踏勘、选点、建标、埋石外业观测（测角、测距、水准、GPS）数据预处理、平差计算仪器设备检校观测原始记录检查编写技术总结报告整理成果资料检查验收WorkflowofcontrolsurveyTechnicaldesignReconnaissanceandstationmarksanglemeasurement,distancemeasurement,levelling，GPSCalibrationofinstrumentsandequipmentInspectionoforiginalobservationrecordsDatapreprocessingandadjustmentcalculationCollateachievementdataPreparetechnicalsummaryreportInspectionandacceptance

导线测量质量检验一、角度闭合差检验二、坐标闭合差检验三、导线全长相对闭合差检验四、导线网质量检验五、测量资料上交InspectionoftraversesurveyInspectionofangularmisclosureInspectionofcoordinatesdifferencesInspectionoffractionaltotallengthdisclosureInspectionoftraversenetworkqualitySubmissionofsurveydata

角度闭合差的检验1、方位角闭合差检验2、导线环内角和检验InspectionofangularmisclosureInspectionofazimuthmisclosureInspectionofgeometricsumofinteriorangles

角度闭合差的检验1、附合导线坐标闭合差的检验2、闭合导线坐标闭合差的检验InspectionofangularmisclosureInspectionofmisclosureincoordinatedifferenceforconnectingtraverseInspectionofmisclosureincoordinatedifferenceforclosedlooptraverse

角度闭合差的检验首先，算出导线全长绝对闭合差WD再以下式算出导线全长相对闭合差f:式中，D为各导线边长。InspectionofangularmisclosureFirstofall,calculatethetotallengthdisclosureWDThenusetheformulabelowtocalculatethefractionaltotallengtdisclosurefDisthelengtofeachtraverseleg
