function union(fc) {
    const args = [];
    geomEach(fc, function (geom) {
        if (geom.type === 'Polygon') args.push(geom.coordinates);
        else geom.coordinates.forEach(function (contour) {
            args.push(contour);
        });
    });
    const unioned = polygonClipping.union(args);
    if (unioned.length === 0) return null;
    else return multiPolygon(unioned);
