Demonstration image

Fix shapes that cross the antimeridian. See the documentation for information about the underlying algorithm. Depends on shapely and numpy.

Can fix:

Usage

shell python -m pip install antimeridian

Then:

```python import antimeridian

fixed = antimeridian.fix_geojson(geojson) ```

We also have some utilities to create bounding boxes and centroids from antimeridian-crossing polygons and multipolygons. See the documentation for a complete API reference.

Command line interface

Use the cli optional dependency to install the antimeridian CLI:

shell python -m pip install 'antimeridian[cli]' antimeridian fix input.json > output.json

Developing

Get uv. Then:

shell git clone https://github.com/gadomski/antimeridian cd antimeridian uv sync

We use pytest for tests:

shell uv run pytest

To build and serve the docs locally:

shell uv run mkdocs serve
