Lines: Code Explain
Lines are represented by LineStrings. LineStrings are simple linear features constructed from a series of points joined by straight lines. Again there are two flavors - one with and one with . The second is the preferred one, but coordinates are still available for GML2 compatibility. Note that in coordinates the X and Y are separated by commas and the coordinates are separated by spaces. In a posList there is an attribute dimension which tells users how many elements there are to each point (that is: is it just X and Y or X, Y, Z) and then each number is separated by a space or a return.
