Specific application of remote sensing technology

In many fields of ocean research, it is necessary to rely on and apply ocean remote sensing data provided by meteorological satellites. Marine researchers can distinguish the position, range, boundary and movement of water masses and currents with different temperatures from the continuous infrared and visible remote sensing images of meteorological satellites, and calculate the movement speed, so as to obtain information such as the distribution of water masses and vortices and the change of currents. This information plays a very important role in marine research, which can not only ensure the safety of navigation, but also save fuel. For example, when a ship sails in the sea ice area. Satellite remote sensing images can be used to select the route of the icebreaker in real time, so that the icebreaker can choose the ice seam or the area with weak ice layer for safe navigation.

2. Application in meteorology and climate research

In weather analysis and forecast, satellite remote sensing data promotes the detection of global atmospheric temperature, making weather analysis and forecast more effective. On the satellite cloud image, we can identify the distribution of various cloud systems according to their size, brightness, boundary shape, texture, horizontal structure and vertical structure, thus inferring the existence and location of fronts, cyclones, typhoons and hail, and successfully tracking and forecasting various large-scale and medium-and small-scale weather phenomena.

3. Application in forestry field

Forestry resources are widely distributed, vast in area and renewable. Remote sensing technology can be used to compile large-scale forest distribution map, calculate forest land area, investigate forest volume and other wild resources, make a three-dimensional survey of barren hills and wasteland suitable for forest, and draw a three-dimensional map of forest land, land use status map and land potential map. Through the dynamic monitoring of forest change, it can play a guiding role in all aspects of forestry production, such as seed collection, seedling raising, afforestation, logging, regeneration and forest product transportation.

4. Application in the field of geology

Remote sensing technology plays an increasingly important role in geological work and has become an important technical means of geological investigation, exploration and monitoring. The application scope has expanded from regional geology, mineral exploration, hydrogeology, engineering geology and environmental geology to agricultural geology, tourism geology, land resources, land use, comprehensive urban survey, environmental monitoring and other fields.
