What are the similarities and differences in the interpretation of aerial remote sensing images and satellite remote sensing images?

***Same points:

1. They are all interpreted by using the spatial characteristics, shape, color, texture, size and other properties of ground objects.

2. Remote sensing images are classified according to the attributes of ground objects, so that people can conduct research and reuse based on the interpretation results.

Differences:

1. The resolution of aerial remote sensing images is higher than that of satellite remote sensing images, so the accuracy of interpretation and classification must be higher, and the categories must be more detailed.

2. Due to the difference in resolution, the areas covered by the two images are different in size. The area covered by aerial remote sensing images is smaller, so the interpretation of satellite remote sensing images focuses more on large scales. classification and changes, while the interpretation of aerial remote sensing images pays more attention to subtle changes on a small scale.

3. Aerial remote sensing images can be interpreted in three dimensions, while satellite remote sensing images can only be interpreted in a plane.

4. Satellite remote sensing images are generally larger in scale than aerial photography, and interpretation of satellite remote sensing images is more difficult than aerial photography.
