How to use remote sensing technology to remotely monitor the growth of trees in Daxinganling area

How to use remote sensing technology to remotely monitor the growth of trees in Daxinganling area, the steps are as follows:

1. There are three main steps in aerial photogrammetry: obtaining the coordinate data of ground control points. The obtained coordinate data of control points are integrated with remote sensing images. Obtain the digital elevation model of the target on the image.

2. Satellite remote sensing technology uses artificial earth satellites as a remote sensing platform to collect and process surface information.

3. Satellite remote sensing technology is widely used in forest pest control, such as forest fires and forest pests.
