Therefore, the 3S technologies are fully applied in the area. On one hand, remote sensing mapping and digital elevation modeling are used to realize highprecision seismic data acquisition and quality control of field operation. GPS control points are emplaced through "firstorder control, survey grid placement stepbystep and overall adjustment", and surface fitting technique is used to build a digital model with regional height anomaly corrected. The GPS RTK and fullstationequipment traverse survey are used to realize the lofting survey of shooting and receiving points. The height fitting of shooting and receiving points of the GPS RTK survey is realized through correcting the digital model with regional height anomaly.
