Parametric Formulas for the JCP Starfish Crop Circle Arc Lengths

Somerset, United Kingdom, is the location of the JCP Starfish crop circle formation analyzed in this dataset. It contains algebraic formulas for fifteen arc lengths derived from the formation's geometry, verified against LibreCAD and SymPy. The dataset includes DXF, TXT, and SVG files totaling 38.6 MB, authored by Rev. Daniel Elis Axelrod and released under CC-BY-4.0 in June 2026.

Use Cases

• Validating geometric reconstructions based on the described pentagonal symmetry and fourteen radii variables.
• Applying symbolic computation scripts for verifying arc length calculations against CAD software.
• Estimating real-world scale and crop damage costs using the described scaling factor and algebra.

Strengths

• Formulas are verified against LibreCAD measurements and SymPy's symbolic computation.
• Includes real-world scaling with a measured outradius of 156.335 feet and a crop damage appraisal using 2025 data.
• Source files (DXF, TXT, SVG) are provided for reuse under a CC0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect the specific geographic and temporal bias of a single crop circle event.
