Which offline correlation source would help airspace monitoring most next?

[cognis-digital]

Now that adsbwatch can flag incursions against offline restricted zones and build pattern-of-life, the next multiplier is richer correlation. Which OFFLINE data would you most want to fuse in (all local, no live services)?

1. Terrain/obstacle fixtures (to flag implausibly-low tracks over terrain).
2. Published airport/runway geometry (approach/departure corridor context).
3. Static RF/receiver-coverage maps (to weight low-confidence positions).
4. Historical baselines per zone ("is this traffic level normal for this hour?").

Trying to prioritize while keeping the strict offline + descriptive-only scope. What would move the needle for your workflow?
