Severe geo-physical or climatic events, including earthquakes, volcanic eruptions, landslides, droughts, floods, cyclones and fire that threaten people or property, are termed natural hazards.
Remote sensing — the science of acquiring information about the Earth using remote instruments, is inherently useful for disaster management.When a disaster strikes, Remote sensing is often the only way to view what is happening on the ground.
At present, earthquakes are hard to predict. But Remote sensing could improve forecasts using Interferometric Synthetic Aperture Radar (InSAR). This technique combines two or more sequential radar images to measure ground motion between them very accurately — on the scale of a few centimetres (or even millimetres). InSAR instruments, such as PALSAR, are already routinely used after earthquakes to assess damage and the extent of ground movement and deformation.
After the LiDAR data is obtained, the data can be post-processed only after data preprocessing. After the data preprocessing, there is a data checking software to conduct a preliminary check on the data results. The general data format check has the follo
Lidar (light detection and ranging) is an optical remote-sensing technique that uses laser light to densely sample the surface of the earth, producing highly accurate x,y,z measurements. Lidar, primarily used in airborne laser mapping applications, is eme
LIDAR (Light Detection and Ranging) technology and processing is used in a wide range of research and practical applications. With its ability to measure dimensions, distances, textures, and many other aspects of targeted subjects, LIDAR processing has be
