Dateline Points Pair

vectorGeoJSONPointEPSG:4326tinybundled

Two points positioned on opposite sides of the antimeridian but very close in real-world distance. Useful for exposing longitude-wrapping clustering and UTM-zone edge logic.

Use this case

import pytest


@pytest.mark.geocase_case("dateline_points_pair")
def test_dateline_points_pair(geocase_case) -> None:
    data = geocase_case.load()
    assert data is not None

What this case checks

Expose logic that treats antimeridian-adjacent points as far apart.

Risk types covered

Expected behavior

Assertion Expected
expect_loadable yes
expect_valid_geometry yes
expect_crs yes
expected_epsg 4326
expected_geometry_types Point

Notes

Two points on either side of the antimeridian that are geographically near each other.
