When set to true, the output image will be in degrees. If this is false, the output image will be in radians.
Type | boolean |
---|---|
Default | false |
Since the slope algorithm depends on cancelling out the units, the conversion factor from the input unit to meters should be set. For example, if the input image DN values mean kilometers, then this value should be 1000 because there are 1000m in one kilometer.
Type | double |

Default | 1.0 |

Image of Vallis Marinaris
Parameter Name:
FROM This is our input image of Vallis Marinaris. The DN values are the angle, in radians, the slope is facing relative to the image. |
