- load(bands: Union[list, BandNames, Callable], resolution: Optional[float] = None, size: Optional[Union[list, tuple]] = None, **kwargs) dict #
Open the bands and compute the wanted index.
The bands will be purged of nodata and invalid pixels, the nodata will be set to 0 and the bands will be masked arrays in float.
Bands that come out this function at the same time are collocated and therefore have the same shapes. This can be broken if you load data separately. Its is best to always load DEM data with some real bands.

- Parameters
bands (list) – Bands and index combination

- is_reference#
If the product is a reference, used for algorithms that need pre and post data, such as fire detection.
- name#
Product true name (as specified in the metadata)
- needs_extraction#
Does this products needs to be extracted to be processed ? (
True
by default).

Product platform, such as Sentinel-2
- product_type#
Product type, satellite-related field, such as L1C or L2A for Sentinel-2 data.
- resolution#
Default resolution in meters of the current product. For SAR product, we use Ground Range resolution as we will automatically orthorectify the tiles.
- sat_id#
Satellite ID, i.e.
S2
forSentinel-2

Sensor type, SAR or optical.
- split_name#
Split name, to retrieve every information from its true name (dates, tile, product type…).
