Forest Twin

The permanent record of every survey of every woodland. Surveys are never overwritten: each approved survey becomes a sealed epoch that can be compared with any other.

What Forest Twin does, and does not, claim

  • Approved surveys are immutable. A re-survey adds an epoch; it never edits an earlier one.
  • A tree present in an earlier survey but not a later one is flagged for review, never reported as felled.
  • Accuracy is reported only against manually measured reference trees, with the sample size shown.
  • Formats read directly here: CSV tree list, GeoJSON tree points. LAS, LAZ, E57 and COPC scans are handled in the point-cloud workspace on each woodland, where processing and reviewed tree extraction run on the external processing worker.
