Abstract

The invention provides a surveying and mapping method, and relates to the technical field of surveying and mapping. The surveying and mapping method comprises the steps of surveying, mapping and planning a surveying and mapping area, arranging a ground control net, a calibration field and measurement control points in the surveying and mapping area, surveying and mapping the surveying and mappingarea in combination with microwave data and satellite positioning data obtained through flight scanning. During the coordinate measurement process of the calibration field and the measurement controlpoints, coordinates can be measured more quickly by adopting the GPS-based real-time dynamic differential method. The work efficiency of ground measurement is improved. Meanwhile, the coordinates of calibration points and measurement control points on the ground can be quickly acquired. The time and the manpower during the surveying and mapping process are saved. Moreover, the method is not influenced by the weather and the surveying and mapping area, so that the adaptability of the surveying and mapping operation to the environment sudden change can be improved.

Description

technical field [0001] The present invention relates to the technical field of surveying and mapping, in particular to a surveying and mapping method. Background technique [0002] Synthetic Aperture Radar (SAR) is an active microwave imaging sensor developed by the U.S. military in the 1950s. It is widely used in aerial remote sensing, aerial survey, aerospace reconnaissance and other fields. Synthetic Aperture Radar Interferometry (InSAR) technology is based on SAR technology, and two SAR images of the same observation area are interferometrically processed to obtain interferometric images, and further obtain high-precision surface elevation information. The current main working mode is to install two radar antennas at a certain distance on the aircraft platform. During work, one antenna transmits radar pulse signals, and the two antennas simultaneously receive the returned pulse waves and image them independently to obtain two coherent images. Good photogram. At the sa...
