Application of GPS and Remote Sensing Image Technology in Construction Monitoring of Road and Bridge

Abstract

Remote sensing technology is superior than the traditional There is nothing comparable to this environmental monitoring and monitoring stations, remote sensing technique has been widely used in the monitoring of air pollution, water pollution, solid waste pollution monitoring, monitoring the change of land use and ecological vegetation changes etc.. The application and development of remote sensing technology in atmospheric monitoring, water quality monitoring and ecological vegetation monitoring are reviewed. GPS is a new type of measurement system, which consists of space constellation, ground control and user equipment. GPS measurement technology has the advantages of high adaptability, high precision and automation. It can be used in many fields such as engineering survey, military, civil traffic navigation, geodetic survey, land use investigation and so on. GPS and modern communication technology combined carrier phase difference method GPS technology is greatly improve the relative positioning accuracy. GPS total station can be widely used in terrain and land surveying and engineering, deformation, surface subsidence monitoring.
