Innovation: Find Useful Storage Format for Historical Analytics

**Describe the task**
Be able to compute an accuracy score for observations over multi month to multi year long timelines.

**Acceptance Criteria**
- [ ] Use a single model (e.g. GFS) to focus the analysis on

**Additional context**
- Geoparquet as an option: https://geoparquet.org/
- Parquet: https://parquet.apache.org/

The issue names no project files, tests, or entry points. Start by tracing how historical observations and analytics data are handled, then compare the stated GeoParquet and Parquet options while focusing on one GFS model. Done means accuracy scores can be computed across multi-month to multi-year timelines using a selected storage format.
