Example 1 with JtsSpatialContextFactory

use of org.locationtech.spatial4j.context.jts.JtsSpatialContextFactory in project traccar by tananaev.

the class GeofencePolygon method calculateArea.

@Override
public double calculateArea() {
    JtsShapeFactory jtsShapeFactory = new JtsSpatialContextFactory().newSpatialContext().getShapeFactory();
    ShapeFactory.PolygonBuilder polygonBuilder = jtsShapeFactory.polygon();
    for (Coordinate coordinate : coordinates) {
        polygonBuilder.pointXY(coordinate.getLon(), coordinate.getLat());
    }
    return polygonBuilder.build().getArea(SpatialContext.GEO) * DEG_TO_KM * DEG_TO_KM;
}

Example 2 with JtsSpatialContextFactory

use of org.locationtech.spatial4j.context.jts.JtsSpatialContextFactory in project ddf by codice.
