What this case checks

Provide a canonical point encoded as Feather so Arrow-backed point loading can be compared against GeoJSON and driver-backed baselines.

Notes

Purpose

Canonical baseline point stored in Feather for Arrow-backed point coverage.

Data

  • Geometry: POINT (12.5 55.7)
  • Attributes: id = 1, name = point_feather_baseline
  • Feature count: 1

Validation

  • Geometry type: Point
  • CRS: EPSG:4326
  • Geometry equals simple_valid_point under shapely.normalize, which is how tests/unit/test_cross_format_canonical.py compares them. The comparison is winding-insensitive by necessity: the Shapefile specification mandates the opposite ring orientation from RFC 7946, and OGR rewrites winding on write. Orientation itself is asserted by shapefile_ring_orientation.

Generation

Generated by scripts/generate_vector_fixtures.py — do not hand-edit. The geometry is derived from params.canonical_source_case_id (simple_valid_point), and generate_vector_fixtures.py --check fails on any drift.

Required capabilities

  • load
  • geometry-validation
  • reprojection
