Class Line

  • public class Line
extends LatLonGeometry
    Represents a line on the earth's surface. You can construct the Line directly with double[] coordinates.

    NOTES:

    1. All latitude/longitude values must be in decimal degrees.
    2. For more advanced GeoSpatial indexing and query operations see the spatial-extras module
