    Interface MatchCandidate

    Validated placement with independent, spatially distributed evidence. The selected query region defines its footprint; partial candidates can rank above complete ones. Geometry, data availability and feature support are separate measurements. Small residuals alone do not imply acceptance or survey accuracy.

    Index
    correspondences: Correspondence[]

    Verified independent pairs retained for review and distributed point application.

    extentStatus: "partial" | "complete"

    Geometric containment with a one-original-reference-pixel boundary tolerance.

    footprint: XY[]

    Entire selected plan boundary in reference pixel coordinates.

    id: string

    Stable opaque identifier; do not use credential-bearing URLs.

    independentInliers: number

    Spatially deduplicated accepted correspondence count.

    inlierRatio: number

    Independent accepted count divided by the footprint's tentative pair count; independent of search-area size.

    medianError: number

    Median forward residual in original reference pixels.

    model: "helmert" | "polynomial1" | "projective"

    Selected similarity, affine or projective model in pixel space.

    overlap: XY[]

    Footprint clipped to the search rectangle, in reference pixels.

    overlapFraction: number

    Clipped plan area divided by full plan area, calculated in query coordinates.

    p95Error: number

    95th-percentile forward residual in original reference pixels.

    rank: number

    One-based position in descending evidence quality.

    referenceDataCoverage: number

    Fraction of full query region with available reference data; alpha is grid sampled.

    score: number

    Versioned ranking measure, not a correctness probability.

    stability: number

    Largest footprint disagreement between spatial split fits, in reference pixels.

    structuralAgreement: number

    Fraction of sampled query edges supported by local reference edges.

    supportCoverage: number

    Query evidence hull area divided by observable query overlap area.

    tentativeMatches: number

    Descriptor pairs of the job whose reference point lies inside this footprint.

    transform: Matrix3

    Row-major homogeneous matrix mapping query edges to reference edges.

    warnings: string[]

    Explanations of ambiguity, extrapolation or missing reference data.
