What exactly is remote sensing for?

When it comes to remote sensing, we have to mention geographic information system. Remote sensing English is remote sensing, geographic information system is geographic information system, and there is a GPS, global positioning system, which everyone is most familiar with. The three systems are collectively called "3s system", which is very clear. If you want to locate yourself or any place accurately in this global village, you need a coordinate to mark the position of the earth, and you need to determine some positions to mark your position. All this information is served by GIS for GPS, and GIS will not fabricate it out of thin air. Where do these materials come from? This requires remote sensing to provide it with original raw data and accurate information of several points.

It can be seen that remote sensing provides basic data services for GIS. If this is the case only in this respect, with the improvement of science and technology, remote sensing has many applications. We can discuss this problem from its definition:

Remote sensing, as its name implies, is a distant perception. Any whole process of obtaining physical or other characteristics such as shape, size, color and temperature without contacting the research object can be called remote sensing. The most obvious example is the human eye. You won't crash because you see there is no danger in front of your car. Some people say blinking doesn't count. Personally, I think so, because there is no connection. One is that it conveys to the other party that you like him, which is purely entertainment ... hahaha, my hand is almost broken, so it is unreasonable not to add extra points. If you want to know more information about the company or domestic enterprises or related disciplines, you can @ me in Weibo of Sina -remosting or send me an email, so since you ask what remote sensing does, I can tell you that it can do many things, such as forest pest control. Mineral exploration, output estimation, weather forecast, etc. All fields of the national economy and people's livelihood have their own talents. At present, the most widely used are weather forecast, lunar exploration and geo-geographic mapping. Most domestic remote sensing technology companies do surveying and mapping. God, my hand is going to break.
