01 / Our approach

For researchers, forest stewards,
and carbon-project teams.

Better decisions begin
with a clearer picture.

01

See the canopy.

Understand forest structure through canopy-height observations. Compare satellite-derived estimates with airborne LiDAR reference data.

Canopy structure
02

Follow the change.

Look across years, not just at a single snapshot. Examine canopy-height change and how well different products capture it.

Change over time
03

Bring evidence forward.

Make model performance and limitations part of the conversation. Build a more informed starting point for forest-health and carbon-project decisions.

Decision context

02 / The foundation

Existing benchmarking platform

Trust starts
with comparison.

Meet CanopyBoard, our foundation for evaluating canopy-height products against airborne LiDAR.

Compare models across spatial scales and inspect temporal validation. Understand where estimates agree with the reference—and where they need a closer look.

03 / From observation to understanding

A connected line of evidence.

  1. 01

    Observe

    Start with satellite observations and reference measurements.

  2. 02

    Compare

    Evaluate canopy-height models against a common reference.

  3. 03

    Track change

    Examine patterns over time and their validation context.

  4. 04

    Inform decisions

    Bring the evidence, and its limitations, into project planning.

04 / The bigger picture

Healthy forests.
Thoughtful decisions.
A longer view.

Forest Ledger’s direction is to connect forest structure and change with the questions that matter to forest stewards and carbon-project teams.

Today, CanopyBoard provides the canopy-height benchmarking foundation. Broader forest-health assessments and carbon-project workflows are the next direction.

Canopy-height validation is not carbon verification. Biomass validation and verified carbon accounting are not current capabilities.
