摘要：The use of airborne global positioning systems (GPS) data in aerial triangulation of parallel strip blocks results in asignificant reduction in the need for ground control. In the case of strip aerial triangulation usually required forhighway corridor mapping, such advantage of using GPS data has not been fully realized. In addition to the costbenefits resulting from the reduction in the ground control, the California Department of Transportation (Caltrans) hasadditional incentive in eliminating serious concerns about the safety of field surveyors exposed to the extreme hazardsof high speed vehicular traffic.The use of an inertial navigation system (INS) in combination with an aerial camera and a GPS receiver has beenreported in order to supplement the GPS data with the camera attitude data during the flight mission. However, nosystematic study to analyze the precision needed for the attitude data has been reported. Therefore, by using simulatedstrip data, the impact of adding the camera attitude control in addition to the airborne GPS data is investigated through asystematic and rigorous error analysis of strip aerial triangulationThe procedure used for the validation of the theoretically derived results through test flights of strip-photography flownat 1:3,000 scale is discussed and results analyzed. Based on this experience, preliminary specifications for practicalimplementation of the use of airborne GPS data for aerial triangulation for highway and other corridor mapping arediscussed.
