PROFILE

Martha Morrissey

Worked on the fieldsoftheworld/ftw-baselines repository to deliver new geospatial data processing features and workflow enhancements for crop calendar and Sentinel-2 satellite imagery. Developed Python-based service logic and CLI tools to compute harvest days from raster data, integrating date conversion utilities and geospatial analysis pipelines. Enhanced the end-to-end workflow by adding EarthSearch as a data source, implementing scene selection with cloud-cover filtering, and orchestrating model inference through a unified command-line interface. Addressed error handling in STAC API queries by introducing validation for future date ranges, improving reliability and user feedback. Emphasized robust testing and production-ready data engineering practices.

September 2025 monthly summary focusing on bug fix for STAC query handling in ftw-baselines. Implemented validation to raise a clear ValueError when a STAC query requests a date range in the future and ensured no attempt is made to query future dates. Added dedicated tests validating the future-date error path, improving reliability, user feedback, and overall system predictability. This work reduces wasted compute and aligns with the product goal of stable, explainable data access across STAC operations.
