odc.geo.math.affine_from_axis

odc.geo.math.affine_from_axis(xx, yy, fallback_resolution=None)[source]

Compute Affine transform from axis.

Transform direction is from pixel coordinates to CRS units of X/Y axis.

Parameters:

xx – X axis coordinates
yy – Y axis coordinates
fallback_resolution (Union[float, int, Resolution, None]) – Resolution to assume for single element axis.

Return type:

Affine

(0,0) in pixel space is defined as top left corner of the top left pixel

Only uses first two coordinate values, assumes that data is regularly sampled.

Raises:: ValueError when any axis is empty.
Raises:: ValueError when any axis has single value and fallback resolution was not supplied.
