A MULTI-SIGNAL WORKFLOW
One research question. Several ways to test it.
Connect an observation to a hypothesis, then check independent evidence before making a decision.
What changed on the ground?
Compare annual crop classes at one coordinate, with boundaries and release dates kept separate.
What is visible in commerce?
Track listing prices and availability; treat displayed purchases as indicators, not certified orders.
Who changed the conversation?
Observe a public post, time-stamp it, and ask an agent for a reviewable market-impact hypothesis.
Research starts with what the data can actually say.
AxisDatum exposes source and observation time alongside the map. Crop pixels are classifications, AIS and ADS-B are received observations, and historical releases are not automatically point-in-time backtest data.
