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.

(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.

Return type

Affine
