SISPPEO 1.1.0 Release Notes

This release includes new features, bug fixes, and a small performance improvement. We recommend that all users upgrade to this version.

A new version of the documentation (hosted using GitHub pages) is also shipped with it.

New features

SISPPEO can now handle multi-variables algorithms

Algorithms that return multiple arrays (/variables) can now be implemented in SISPPEO. For instance, you can now return :

• the variable of interest + its uncertainty ;

• a given variable (e.g., the absorption coefficient of CDOM) at several wavelengths.

This feature will (soon) be used to add an algorithm that estimates Kd [transparency] using QAA (Lee, 2002) for L8 and S2. It will be a multi-var algorithm returning Kd at 443, 490, 550, and 660 nm.

Added a new reader for handling C2RCC (C2X, C2X-COMPLEX) products

C2RCC products (generated with Snap) can now be use as input products.

⚠️ a temporary argument "date" is currently used because of the absence of metadata in C2RCC products. Therefore, C2RCC products can not be used for batch processing.

A new (water quality) algorithm is available

NDCI (Normalized Difference Chlorophyll Index) [chl-a]

New CLI commands and alias

• commands:

  • algorithms -> returns the list of algorithms that can be used.

  • masks -> returns the list of masks that can be created.

  • create-l3 to create [masked] products

• option alias:

  • -i for --input_product

  • -t for --product_type

  • -im for --input_product_mask

  • -tm for --product_type_mask

  • -a for --algo

  • -m for --mask

  • -o for --out_product

New timelapse method

Added a method to generate timelapses (as gif files) from TimeSeries objects.

Improvements

• GRSReader can now read L4, L5, L7 and L8 products.

• extract_points :

  • can now be use with L3MaskProducts ; the method has been moved from L3Product to CoordinatesMixin.

  • returns NaN instead of 0 in corners (if a rounded buffer is used).

• L3Product.plot : you can choose the variable to be plotted.

• added SWIR bands specs to both L8 and S2 in sat_config.yaml

• improved the readibility of the code by using nametuples

• updated error messages of xy and index methods.

Performance improvements

Improved both the readibility and the memory efficiency of the code with the use of dataclasses and slots.

Changes

• got rid of the ObjectFactory class and used dictionnaries instead.

• loaded TimeSeries ObjectFactory cla (from multiple files) now use a xarray.DataArray instead of a xarray.DaskArray.

• extract_points has a new signature.

Bug fixes

• filenames of output products

• use of nanmedian in TimeSeries.compute_stats

• image encoding (for empty or small images)

• batch processing

• Mutex class (CLI)

Dependencies

pip is not used anymore (for installing pvlib, ray and s2cloudless) in the environment.yaml conda file. Instead, pvlib-python, ray-core, and s2cloudless librairies (availables on conda-forge) are used.

SISPPEO v1.0

This is the first official release of SISPPEO.
