The platform

Freyra Evidence Workspace. One evidence chain per project.

The platform brings together field data, public data and expert verification so that every conclusion can be traced back to its source. Not a dashboard with impressive figures. A working tool with traceability.

The evidence chain
Drone imagery
Field and drone data with GPS
Public data
Maps, soil, weather and satellite data
Verification
AI-assisted and professional assessment
Baseline
Versioned report and evidence package
Planting
Suitability for each land area and follow-up
Each step is versioned and can be traced back to its source.
The evidence chain

Every claim can be traced back to its source.

An evidence chain connects field data, public data, calculations and expert assessments. When someone asks why, you can show them.

Field data with GPS

Drone photographs and reference photographs with location and time from EXIF data.

Public data

Retrieved automatically from Danish data sources and linked to the specific site.

Versioning

Every change is saved as a new version with a timestamp and the person responsible.

SHA-256 fingerprints

Evidence packages receive a digital checksum so that it is possible to document that they remain unchanged.

The workflow

From drone photograph to baseline in four steps.

The images are our own drone photographs.

Watercourse with open water and vegetation, viewed from a drone
Photo points are positioned using the image's GPS data.
Watercourse through grass and vegetation, viewed from a drone
Public data is retrieved for the area.
Watercourse corridor between fields, viewed from a drone
Drone photographs and public data are compared and assessed by experts.
Watercourse between meadow and vegetation, viewed from a drone
The baseline is compiled in a versioned report.
Data sources

Built on public Danish data.

We retrieve data from established sources, using the same basis as authorities and advisers.

Dataforsyningen

Orthophotos, cadastral data and the Danish elevation model (DHM).

Danmarks Arealinformation

Natural and protected areas registered under § 3 (Danish nature protection legislation).

GEUS

Soil type and lowland maps.

DMI

Weather data to provide context for field observations.

Copernicus Sentinel-2

Satellite imagery for vegetation and land cover.

Verification

AI assists. People assess.

The material is first reviewed automatically to identify what needs attention. A specialist then assesses the result before it becomes part of the baseline. Every conclusion is backed by an expert assessment.

  • Automated review flags deviations and areas that need a closer look
  • Expert assessment of each point before it becomes part of the baseline
  • An audit trail shows what was assessed, by whom and when
Repeat observation points

During the initial survey, we establish fixed positions using GPS. On return visits, photographs are taken from the same points so that before-and-after material can be compared directly.

Audit trail

Every data point, calculation and assessment in an evidence package has a source, a timestamp and a person responsible. This is what makes the package verifiable.

Planting suitability

Suitable, conditional or unsuitable. With reasons.

The planting analysis is rule-based and draws on soil, water, protected areas and existing natural habitats. Each site receives an assessment in hectares, with reasons and source references.

Effects are shown as ranges from the research literature, not as promises. This makes the assessment suitable for dialogue with landowners, advisers and the Green Tripartite (Grøn Trepart).

Suitable

Conditions support planting without specific reservations.

Conditionally suitable

Planting is possible subject to specific conditions, which are described.

Unsuitable

Conditions argue against planting, for example protected natural habitats or lowland areas.

Access

Login for the municipality.

Your team gets login access to its own projects, with a version history and evidence package sharing. The material is held with you, not in an inbox.

Controlled access

The municipality or project owner controls who has access. Data is not shared with others without your consent.

FAQ

Frequently asked questions

Would you like to see the platform with your own site?

A pilot project starts from DKK 125,000 and demonstrates the entire evidence chain in practice.
