-If no [proejction](~${componentNameInLink}.projection) is applied, the latitudes and longitudes in GeoJSON are linearly mapped to pixel coordinates diarectly. `aspectScale` offers a simple way to visually compensates for the distortion caused by the fact that the longitudinal spacing shrinks as latitude increases. For example, an `aspectScale` can be roughly calculated as `aspectScale = Math.cos(center_latitude * Maht.PI / 180)`, which is similar to a sinusoidal projection.
