resample_chunk_to_sensor ¶

resample_chunk_to_sensor(chunk: ndarray, wavelengths: ndarray, sensor_srf: Dict[str, ndarray]) -> np.ndarray

Resample a hyperspectral chunk to target sensor bands using SRFs.

Parameters:

Name	Type	Description	Default
`chunk`	`ndarray`	Hyperspectral reflectance cube with shape `(y, x, bands)`.	required
`wavelengths`	`ndarray`	Wavelength grid aligned to the last axis of `chunk`.	required
`sensor_srf`	`Dict[str, ndarray]`	Mapping of sensor band name to spectral response sampled on `wavelengths`.	required

Returns:

Type	Description
`ndarray`	Resampled cube with shape `(y, x, len(sensor_srf))` and dtype `float32`.
