NASA SISTER Project: Experimental Workflows and Sample Data for Earth Imaging Spectroscopy

NASA's SISTER project developed prototype workflows and data products in support of the upcoming Surface Biology and Geology mission. This collection contains experimental Common Workflow Language (CWL) files, Jupyter Notebooks, and sample data products based on AVIRIS-CL airborne instrument data. The provided algorithms and sample products are experimental placeholders and are not intended for scientific use.

Use Cases

• Testing portable and reproducible data processing workflows based on the described Common Workflow Language (CWL) files.
• Prototyping community algorithms for terrestrial, aquatic, and snow ecosystem analysis as mentioned in the description.
• Experimenting with end-to-end processing systems for imaging spectroscopy data from instruments like AVIRIS-CL.
• Developing standards-compliant (OGC) application packages for geospatial data processing.

Strengths

• Workflow design emphasizes being open, portable, scalable, standards-compliant, and reproducible.
• Includes multiple components: CWL process files, Jupyter Notebooks, archived algorithm steps, and sample data products.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Sample data products are explicitly labeled as experimental, not validated, and not intended for scientific use.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
