如何利用遥感进行灾害应对和救济？

遥感可以多种方式用于灾害反应和救灾。它可用于探测和监测自然灾害，如洪水、飓风、地震、山体滑坡和森林火灾。遥感还可用于评估损害程度，并提供有关受影响地区的位置和大小的信息。此外，遥感还可用于绘制受灾地区的详细地图，为搜索和救援行动提供有价值的信息。

How can remote sensing be used for disaster response and relief

       Remote sensing can be used for disaster response and relief in a number of ways. It can be used to detect and monitor natural disasters, such as floods, hurricanes, earthquakes, landslides, and forest fires. Remote sensing can also be used to assess the extent of the damage and provide information on the location and size of affected areas. In addition, remote sensing can be used to create detailed maps of disaster-affected areas, providing valuable information for search and rescue operations.
