EC-M-1.1 v0.3.0 Research

Restoration Trajectory RT

Multi-year ecological-condition trajectory for a parcel under active restoration.

A time-series product specifically for restored properties. Tracks ECI evolution against a synthetic-control baseline of comparable unrestored parcels in the same biome, with confidence intervals. Built for restoration-MRV and for impact-fund reporting.

Twelve-month sample series

A representative parcel under EC-M-1.1, July 2025 through June 2026. The line is the published value at each monthly vintage; the band is the 95% confidence interval. Past vintages are immutable — this same chart, queried in 2040, returns the same values.

How to query

The signal is queried at the canonical /v1/signals/{id} endpoint. Required parameters are a location and an as-of date. The same query replayed in 2040 returns the same value.

curl https://api.earth-signals.com/v1/signals/restoration-trajectory \
  -H "Authorization: Bearer es_preview_..." \
  -d "lat=44.4654" \
  -d "lng=-72.6874" \
  -d "as_of=2026-04-30"

Endpoint and tokens shown for spec illustration. The Earth Signals API is in private beta with named design partners; the underlying Earth API and Calculator API are live.

The full parameter table — point query, parcel id, polygon aggregation, methodology pinning — is in the API reference.
