xdem.DEM.from_array#

classmethod DEM.from_array(data, transform, crs, nodata=None, vcrs=None)[source]#

Create a DEM from a numpy array and the georeferencing information.

Parameters

data (ndarray[Any, dtype[floating[Any]]] | MaskedArray[Any, dtype[floating[Any]]]) – Input array.
transform (tuple[float, ...] | Affine) – Affine 2D transform. Either a tuple(x_res, 0.0, top_left_x, 0.0, y_res, top_left_y) or an affine.Affine object.
crs (UnionType[CRS, int, None]) – Coordinate reference system. Either a rasterio CRS, or an EPSG integer.
nodata (UnionType[int, float, None]) – Nodata value.
vcrs (Union[Literal['Ellipsoid'], Literal['EGM08'], Literal['EGM96'], VerticalCRS, str, Path, int, None]) – Vertical coordinate reference system.

Return type

DEM

Returns

DEM created from the provided array and georeferencing.
