Signal catalog · Methodology EC-M-1.1 · Private beta

The structured-data layer for Earth.

Versioned, lineage-tracked ecological signals — for the institutions that price, study, regulate, insure, and restore the natural world.

Built on the Landseed measurement stack: the Earth API, the Calculator API, and the EC-M-1.1 methodology. Every observation is signed, vintaged, and joinable to its upstream computation graph.

Why this is different

Numbers that never change underneath you.

Most ecological data quietly changes when the methodology evolves — and a paper, a regulator filing, or an insurance contract built on it can't be re-checked later. Earth Signals is built the opposite way. Every observation is dated, signed, and locked the moment it's published. The number you cite today is the number anyone else can verify in 2040.

  1. 01

    Permanent

    Every published number is locked the moment it ships. New methodology versions create new numbers; the old ones never move.

  2. 02

    Traceable

    Every number traces back to its exact inputs. Anyone can click through and see the source data, the methodology, and the math.

  3. 03

    Signed

    Every number is cryptographically signed at publish. Strong enough for litigation, regulator filings, and contract settlement.

  4. 04

    Consistent

    A scientist, a regulator, and an insurance carrier all read the same number in the same shape. No surface-specific drift.

The platform at a glance

One catalog. Three ways to read it.

Access

Three doors into the same catalog.

The methodology is identical across tiers. What differs is licence, governance, SLA, and price.
