# 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.
