Characteristics and advantages of remote sensing technology

The characteristics of remote sensing technology-wide monitoring range and global coverage; Instantaneous imaging, real-time transmission, rapid processing, rapid information acquisition and dynamic monitoring, less affected by the ground.

1. Wide detection range: China only needs more than 600 Landsat images to cover all of them.

2. The speed of data acquisition is fast and the cycle is short: field surveying and mapping is repeated for several years, more than ten years or even decades. Aerial photogrammetry can only be repeated every few years. Land satellites can cover the earth once every 16 days.

3. Less limited by ground conditions: For areas with harsh natural conditions and difficult ground operations, such as mountains, glaciers, deserts, swamps, or areas that are difficult to reach because of national boundaries, it is easier to obtain information through remote sensing, especially space remote sensing.

4. There are many means and a large amount of information is obtained: different bands and different remote sensing instruments are selected to obtain the required information. Guangxi Tu Shan technology co., ltd
