Claim

The study mapped six natural and seminatural open wetland types across large parts of Europe at 10-m resolution, estimating 413,504 ± 17,782 km2 with overall accuracy of 96.6 ± 0.3%.

Score: 0.7146 under ledger-default@0.3.0 at snapshot 27745

3 of 4 review checks done · 1 counted · 2 by the author only

Main unresolved issue: 7 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:c61a0522-abe4-8166-ac54-e8997fc5550c

Not yet independently audited.A quoted passage from nature.com was not found on the page when Galedra fetched it.

Why?

Strongest counted support: A University of Copenhagen release independently describes the six-category, 38-country wetland map at 10-metre resolution. weight 0.918000 evidence

Suppressed as dependent: The supplied passage directly reports six wetland types, 10-meter resolution, the mapped area estimate, and overall accuracy.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Leans supported to Leans contradicted.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

Under neighbouring settings of the same model: 0.6553 to 0.7673, a spread of 0.1120.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.
