# Types of corrections

Uncorrected image
Corrected image

Once an image is acquired several types of corrections can be applied:

Radiometric corrections

- Atmospheric corrections
  - Dark pixel correction (relative)
  - Physics based correction (absolute)
- Sun glint correction
- Air/water interface correction
- Depth correction

Geometric corrections

When do you need to correct?
