function slope(in_src, out_dst, compute_edges = None, band = 1, scale = 1.0, use_degree = True, algos = "Horn", **kwargs):

Calculate slope from any supported DEM raster file!

Parameters:

in_src: str.

The input raster file path.

out_dst: str.

The output raster file path.

Optional:

compute_edges = bool. Default True.

Whether to compute raster edge data and data near no data values.

Setting values that are not True are treated as False.

band = int. Default 1.

Number of the element calculation band. Start with 1.

scale = float. Default 1.0.

The ratio of vertical units to horizontal. If the vertical unit is m and the horizontal unit is ��, you can set Scale = 111120.

use_degree = bool. Default True.

Whether to use degrees (��) for slope. If false (False), the slope is expressed as a percentage (%).

algos = str. Default 'Horn'.

Surface algorithm. May be 'Horn' or 'ZevenbergenThorne'.

**kwargs:

Other parameters passed to translate.

Returns:

Type: DataSet.
