Some very strong cartographic traditions that are unavailable or difficult in GL:
- Highlight a specific country with a lighter background and/or more detail
- Simplify highway junctions into one junction point (e.g., a white diamond and no links)
- Fill large highway interchanges with the highways’ line color
- Duplex shields
- Adjacent route shields for roads belonging to multiple route networks
- Different state route shields in each state
- County route shields
