static fromNumpyArray(mapXAsMaskedNumpyArray, mapYAsMaskedNumpyArray)

static from_2dmaps(mapX, mapY)

Build a Slopes object from X/Y 2D maps or a series of X/Y 2D maps. Both maps must be np.ma.MaskedArray objects. Masks for X and Y slopes must be identical.

Parameters:

• mapX (np.ma.MaskedArray) – 2D slope map

• mapY (np.ma.MaskedArray) – 2D slope map

Returns:

slopes – A new Slopes object. Valid slopes (as indicated by the mask) are copied into an internal array. No references to the input data are kept.

Return type:

Slopes object
