Web Mercator Baseline Point

vectorGeoJSONPointEPSG:3857tinybundled

A point in EPSG:3857 (Web Mercator). Baseline for the CRS mismatch that arises when projected metre coordinates are treated as degrees.

Point geometry of web_mercator_baseline, rendered from the case's data
Point 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("web_mercator_baseline")
def test_web_mercator_baseline(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]"

View GeoCase on PyPI.

What this case checks

Ensure vector loading and downstream utilities handle a baseline Web Mercator point with explicit projected CRS metadata.

Risk types covered

Expected behavior

Assertion Expected
expect_loadable yes
expect_valid_geometry yes
expect_crs yes
expected_epsg 3857
expected_geometry_types Point

Notes

Baseline EPSG:3857 point for projected-vector coverage.

Required capabilities

  • load
  • geometry-validation
