antimeridian 0.3.4

Fix GeoJSON geometries that cross the antimeridian

antimeridian

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

Can fix:

• Shapely Polygon, MultiPolygon, LineString, and MultiLineString objects
• GeoJSON Polygons, MultiPolygons, Features and FeatureCollections, as dictionaries
• Anything that has a __geo_interface__

Usage

pip install antimeridian

Then:

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:

pip install 'antimeridian[cli]'
antimeridian fix input.json > output.json

Developing

Clone and install in editable mode with the development optional dependencies:

git clone https://github.com/gadomski/antimeridian
cd antimeridian
pip install -e '.[dev,docs]'

We use pytest for tests:

We use Sphinx for docs:
