Layer QC
When To Use
- Use after ingestion and before modeling or map publication.
- Use when layers are assembled from multiple teams or ETL jobs.
- Use when analysis quality is sensitive to geometry and attribute integrity.
Workflow
- Verify geometry validity and detect null or empty features.
- Check required fields, types, and missing-value rates.
- Validate extents, resolution, and expected feature counts.
- Detect duplicates, outliers, and inconsistent category values.
- Emit a pass/fail summary with remediation actions.
Guardrails
- Do not continue silently with invalid geometry on critical paths.
- Flag data drift when schema or counts differ from expected baselines.
- Keep QC outputs machine-readable for replay and automation.
