Equator Crossing Line

vectorGeoJSONLineStringEPSG:4326tinybundled

A WGS84 LineString crossing latitude 0 to expose equatorial edge cases and sign-change assumptions in coordinate handling.

LineString geometry of equator_crossing_line, rendered from the case's data
LineString geometry, rendered from the case's actual geometry. Scale is normalized to the viewport and is not comparable between cases.

Use this case

import pytest


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

Use GeoCase in your tests

Install the complete set of vector, raster, and NetCDF dependencies:

pip install "geocase[all]"

What this case checks

Ensure line-based workflows can process geometries that cross the equator without coordinate sign mistakes.

Risk types covered

Expected behavior

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

Notes

Simple LineString crossing the equator for geographic boundary coverage.
