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.
On the afternoon of April 30, the first press conference of the 2020 Mount Everest elevation measurement was held at the Everest Base Camp, and the 2020 Mount Everest elevation measurement was officially launched. This year marks the 60th anniversary of the first successful summit of ...
With the continuous development and progress of earth observation technology, and the continuous diversification of means for obtaining spatial information, the use of a single means of spatial data resources has been difficult to meet people's information needs. Lidar and hyperspectral ...
t present, airborne LiDAR technology has made great progress and has been widely used in many fields. Following the trend of technology development, feiyan remote sensing has long been in the forefront of the industry.
