====== Calc Slope Map ====== 

===== Description =====

This functor calculates a slope map based on a height map.

===== Inputs =====

^ Name  ^ Type  ^ Description  ^
| Elevation | [[Map Type]]  | A height map. The height is assumed to be in meters. It may have null values.   |

===== Optional Inputs =====

^ Name  ^ Type  ^ Description  ^ Default Value  ^
| Use Diagonals Are Longer  | [[Boolean Value Type]]  | Indicates if the distance between the cells at the diagonals must be increased by the factor of 1.414213562.  | True  |
| Slope In percent  | [[Boolean Value Type]]  | If true, the slope will be calculated in percent; otherwise, it is calculated in degrees.  | False  |
| Cell Type  | [[Cell Type Type]]  | The slope data cell type.  | Signed 32 Bit Integer  |
| Null Value  | [[Null Value Type]]  | Null value of the slope map. | Default  |
| Slope Is Sparse  | [[Boolean Value Type]]  | If true, set the output map as sparse.  | False  |

===== Output =====

^ Name  ^ Type  ^ Description  ^
| Slope  | [[Map Type]]  | The slope map. Map format has the same dimensions of the source map.  |

===== Group =====

[[Functor List#Map Algebra | Map Algebra]]

===== Notes =====

The functor calculates the slope of a cell using the height difference for each neighbor cell and its dimension. The largest slope is chosen as the output value.
