How to read this

Each distance compares the two windows in its own units; lower is more similar. Families are never summed or ranked together.

Not compared on this card: Radar CPR (radar unavailable for body), Model embedding (encoder not evaluated).

What it could help investigate
Assumed Scenario input, tolerance or unverified physical simplification

Assumed: this Earth window could help investigate how surfaces with comparable supported descriptors (terrain_relief, terrain_texture) behave, as a candidate window identified by this search for the Mars target. It is an interpretation to test, not a measured result.

Proposed field test
ProposedAssumed Scenario input, tolerance or unverified physical simplification

Proposed, not yet carried out: survey a surface patch in this Earth window with a clast-size and coverage distribution, material and moisture notes, and calibrated radar observations under controlled geometry. Dimensions and sampling would be chosen for the sensor and site; none of these measurements has been made.

Scope of this card
  • candidate window identified by this search; not a proven analog
  • Copernicus GLO-30 heights are a digital surface model including vegetation and buildings, referenced to EGM2008 (PRD 5)
  • Mars target: terrain only, radar unavailable for this body
  • the encoder is EXPERIMENTAL and not used in any ranking
  • WorldCover v200 2021 land-cover mask, nearest class at 90 m centres (ANA-05 default)
  • No published elevation-error clone set exists for this target's DTM, so measurement error is Unavailable and no tie is claimed; scenario ranks come from mask and region filters only.
  • Mars targets are compared on terrain only; no radar product is used.
  • Mode C: radar comparison not completed. The radar inputs were not qualified within the pilot, so no radar distance or radar signature is part of this card.
  • The encoder is EXPERIMENTAL (G5 FAIL) and takes no part in any ranking; its distance, if shown, is Predicted.
  • Field confirmation is future work; similarity here does not establish block sizes, soil strength, buried structure or low-gravity mobility (PRD 3).
