Coordinate Index Values
coordIndex [ 1, 0, 3, -1, . . . ]
- Indexes reference ordered points of
coord field
- Index order is arbitrary (eg: 1, 0)
- Indexes are Zero-based (eg: 0)
- Can skip coordinates (eg: 0, 3)
- Poly-line can be many points (eg: 1, 0, 3)
- End of poly-line (eg: -1)
- Multiple poly-lines (eg: . . .)
