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.

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.
