    • toLineOrPoint

      public static org.locationtech.jts.geom.Geometry toLineOrPoint(org.locationtech.jts.geom.Coordinate[] coords, org.locationtech.jts.geom.GeometryFactory fact)
      Converts an array of coordinates to a line or point, as appropriate.
      Parameters:
      coords - the coordinates of a line or point
      fact - a factory used to create the Geometry
      Returns:
      a line if there is more than one coordinate; a point if there is just one coordinate; an empty point otherwise

    • equals

      public static boolean equals(org.locationtech.jts.geom.Coordinate[] coord1, org.locationtech.jts.geom.Coordinate[] coord2)

    • fromCoordinateArrays

      public static List<org.locationtech.jts.geom.Geometry> fromCoordinateArrays(List<org.locationtech.jts.geom.Coordinate[]> coordArrays, org.locationtech.jts.geom.GeometryFactory fact)
      Converts a collection of coordinate arrays to a collection of geometries.
      Parameters:
      coordArrays - a collection of Coordinate[]
      fact - a factory used to create the Geometries
      Returns:
      a collection of LineStrings and Points

    • addCoordinateArrays

      public static void addCoordinateArrays(org.locationtech.jts.geom.Geometry g, boolean orientPolygons, List<org.locationtech.jts.geom.Coordinate[]> coordArrayList)
      Extract the coordinate arrays for a geometry into a List.
      Parameters:
      g - the Geometry to extract from
      orientPolygons - whether or not the arrays in the List should be oriented (clockwise for the shell, counterclockwise for the holes)
      coordArrayList - the List to add the coordinate arrays to

    • ensureOrientation

      public static org.locationtech.jts.geom.Coordinate[] ensureOrientation(org.locationtech.jts.geom.Coordinate[] coord, int desiredOrientation)
      Sets the orientation of an array of coordinates.
      Parameters:
      coord - the coordinates to inspect
      desiredOrientation - CGAlgorithms.CLOCKWISE or CGAlgorithms.COUNTERCLOCKWISE
      Returns:
      a new array with entries in reverse order, if the orientation is incorrect; otherwise, the original array

    • toCoordinateArrays

      public static List<org.locationtech.jts.geom.Coordinate[]> toCoordinateArrays(org.locationtech.jts.geom.Geometry g, boolean orientPolygons)
      Extract the coordinate arrays for a geometry. Polygons will be checked to ensure their rings are oriented correctly. Note: coordinates from Points or MultiPoints will not be extracted.
      Parameters:
      g - the Geometry to extract from
      orientPolygons - ensure that Polygons are correctly oriented
      Returns:
      a list of Coordinate[]
