PROFILE
Isabelle Wittmann
Worked on the IBM/terratorch repository to enhance the reliability and maintainability of its embedding notebook and documentation. Updated the Jupyter notebook to use terratorch library version 1.2.4, enabling access to the latest embedding features and ensuring compatibility with ongoing machine learning workflows. Addressed documentation accuracy by correcting a hyperlink in the CONTRIBUTING.md file, improving onboarding and reducing user friction. All changes were tracked with precise, auditable commits, supporting traceability and easier rollback if needed. Leveraged Python, Markdown, and version control throughout the process, focusing on clear, incremental improvements that support both end users and future contributors to the project.

Feb 1, 2026February 2026 — IBM/terratorch: substantive business-value advances across temporal embeddings, multimodal data workflows, geospatial capabilities, and CI/CD/docs. Implemented temporal embedding enhancements for AggregateTokens including pooling controls and 4D tensor handling; refactored feature extraction neck to use rearrange for better spatial-temporal data processing. Enhanced multimodal data loading with CSV embeddings export, subdirectory loading, and a generic 'prefix' parameter with robust prefix/path handling. Added geospatial capability with a new Sentinel-2 ResNet backbone configuration via torchgeo softcon. Strengthened documentation and CI/CD by syncing with main, adding issue templates, Dependabot config, and workflows for docs and tests. These changes improve data ingest scalability, experiment throughput, reproducibility, and geospatial modeling capabilities.
