Input raster | The input surface raster. | Raster Layer |

Output measurement (Optional) | Determines the measurement units (degrees or percentages) of the output slope raster. - Degree—The inclination of slope will be calculated in degrees.
- Percent rise—The inclination of slope will be calculated as percent rise, also referred to as the percent slope.
| String |

Z factor (Optional) | The number of ground x,y units in one surface z-unit. The z-factor adjusts the units of measure for the z-units when they are different from the x,y units of the input surface. The z-values of the input surface are multiplied by the z-factor when calculating the final output surface. If the x,y units and z-units are in the same units of measure, the z-factor is 1. This is the default. If the x,y units and z-units are in different units of measure, the z-factor must be set to the appropriate factor or the results will be incorrect. For example, if the z-units are feet and the x,y units are meters, you would use a z-factor of 0.3048 to convert the z-units from feet to meters (1 foot = 0.3048 meter). | Double |

Method (Optional) | Specifies whether the calculation will be based on a planar (flat earth) or a geodesic (ellipsoid) method. The planar method is appropriate to use on local areas in a projection that maintains correct distance and area. It is suitable for analyses that cover areas such cities, counties, or smaller states in area. The geodesic method produces a more accurate result, at the potential cost of an increase in processing time. - Planar—The calculation will be performed on a projected flat plane using a 2D Cartesian coordinate system. This is the default method.
- Geodesic—The calculation will be performed in a 3D Cartesian coordinate system by considering the shape of the earth as an ellipsoid.
| String |

Z unit (Optional) | The linear unit of vertical z-values. It is defined by a vertical coordinate system if it exists. If a vertical coordinate system does not exist, the z-unit should be defined from the unit list to ensure correct geodesic computation. The default is meter. - Inch—The linear unit will be inches.
- Foot—The linear unit will be feet.
- Yard—The linear unit will be yards.
- Mile US—The linear unit will be miles.
- Nautical mile—The linear unit will be nautical miles.
- Millimeter—The linear unit will be millimeters.
- Centimeter—The linear unit will be centimeters.
- Meter—The linear unit will be meters.
- Kilometer—The linear unit will be kilometers.
- Decimeter—The linear unit will be decimeters.
