Example 1 with GeometryCollection

use of com.mapbox.geojson.GeometryCollection in project mapbox-java by mapbox.

the class TurfMetaTest method coordAllGeometryCollection.

@Test
public void coordAllGeometryCollection() throws TurfException {
    List<Point> points = new ArrayList<>();
    points.add(Point.fromLngLat(1.0, 2.0));
    points.add(Point.fromLngLat(2.0, 3.0));
    LineString lineString = LineString.fromLngLats(points);
    List<Geometry> geometries = new ArrayList<>();
    geometries.add(points.get(0));
    geometries.add(lineString);
    BoundingBox bbox = BoundingBox.fromLngLats(1.0, 2.0, 3.0, 4.0);
    GeometryCollection geometryCollection = GeometryCollection.fromGeometries(geometries, bbox);
    FeatureCollection featureCollection = FeatureCollection.fromFeature(Feature.fromGeometry(geometryCollection));
    assertNotNull(featureCollection);
    assertNotNull(TurfMeta.coordAll(featureCollection, true));
    assertEquals(3, TurfMeta.coordAll(featureCollection, true).size());
    assertEquals(1.0, TurfMeta.coordAll(featureCollection, true).get(0).longitude(), DELTA);

}

Example 2 with GeometryCollection
