Nordic Cross Family Membership Checker
Audit Nordic Cross Family Membership Checkervisual-feature annotations, not an image detector, official family membership or geographic/political identification. Feature columns, independently annotated in order: full spanning orthogonal cross, vertical stem toward hoist, hoist/top coordinates verified. Unknown evidence and compatible classes retained; not automated semantic, historical, identity, legal or safety determination.
Description
A Nordic-cross pattern combines a spanning orthogonal cross with a stem toward the hoist.
A Nordic-cross pattern combines a spanning orthogonal cross with a stem toward the hoist.1
This checker reviews three independent layout annotations rather than inferring a regional identity.
When to use Nordic Cross Family Membership Checker
Use this tool when you need to review independently annotated design features against a fixed pattern. Establish the flag dimensions, orientation, specification, palette, or visual annotations needed for this particular calculation.
How to use Nordic Cross Family Membership Checker and understand its results
- Establish the flag dimensions, orientation, specification, palette, or visual annotations needed for this particular calculation.
- Enter observedFeatureFlags, featureKnownFlags, following the field table and rules below, then run the tool.
- Read result. Use the output meanings below to interpret units, signs, flags, and any nested result fields.
- Correct reported input issues and run again. For a successful result, check the stated evidence coverage and assumptions before using it in your review.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedFeatureFlags | Observed feature flags | list of number | Required |
| featureKnownFlags | Feature known flags | list of number | Required |
Enter binary observed-feature and feature-known lists in the fixed column order listed below. Their length must match the fixed rules. Known mismatches exclude a candidate; unknown columns leave it compatible. A candidate is witnessed only when every required column is known and matches. Ignored columns do not require evidence. Return compatible classes, witnessed classes, and zero-based unknown-feature indices. This consumes annotations, not pixels.
compatible_c=∀j(rule_cj=−1 or known_j=0 or feature_j=rule_cj); witnessed_c=∀j(rule_cj=−1 or (known_j=1 and feature_j=rule_cj)) Symbols follow the input and output meanings and the calculation rules above.
Fixed feature-column order: full spanning orthogonal cross, vertical stem toward hoist, hoist/top coordinates verified.

}Limitations and assumptions
Annotations must be independently established. Candidate labels describe only the fixed tested features; they are not country identification, official membership, or an image-recognition result.
Missing required fields, unknown fields, wrong types, and violated calculation rules are input issues. Numeric values must be finite; nonfinite results are rejected. Evidence arrays must be dense, with no missing cells. Numeric observation lists allow at most 10,000 entries, subject to any smaller bounds stated above. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related review, use Nordic Cross Offset Position Calculator: A Nordic-cross construction needs a horizontal position and an arm width in a declared flag rectangle. This tool scales a verified vertical-stem offset and centers the horizontal arm on the hoist. For a complementary step, use Symmetry Type Classifier (vertical/horizontal/rotational): A flag may exhibit vertical reflection, horizontal reflection, and half-turn symmetry at the same time. This checker keeps every symmetry supported by independent observations.
