This paper introduces a new wavelet transform based method of road centerline extraction from high resolution remote sensing images. In the one dimensional case, we characterize different kinds of sudden changes of signals by comparing the magnitudes of the local extreme values of the wavelet transforms under different dilation scales of the same wavelet. The platform-like signals, which come f...

Loess geological tunnels are characterized by weak structure and poor self-stability of surrounding rock, so effectively controlling the excavation face distances different caverns is great significance for guiding safe construction large-section tunnels. Based on loess tunnel from Xi’an Metro Line 4, optimal distance determined based Midas numerical model. Then, surface settlement horizontal d...

Monitoring of rivers is major scientific and societal importance due to the crucial resource they provide human activities threats caused by flood events. Rapid revisit synthetic aperture radar (SAR) sensors such as Sentinel-1 or future surface water ocean topography (SWOT) mission are indispensable tools achieve all-weather monitoring bodies at global scale. Unfortunately, spatial resolution t...
