When to correct
The table below indicates the types of corrections that must be applied depending on the desired end use for your image.
| Type of use | Geometric correction | Radiometric correction | Atmospheric correction* | Other corrections** |
|---|---|---|---|---|
| Wall hanging / quick look |  |
|
|
|
| Link to field, spatial, GIS data |  |
|
|
|
| Biophysical maps e.g. Temperature | |
|
|
|
| Link to field reflectance data, change detection | |
|
|
|
| Improved accuracy of above | |
|
|
|
* Atmospheric correction can be relative (dark pixel correction) or absolute (physics based correction).
** Other corrections include removal of bi-directional reflectance, sun glint and cross track illumination.
