Location of Example: 152°50'22" East, 25°59'32" South
Distinctive Characteristics:
  • Road bridges generally cross bodies of water, or low lying areas along the road network.
  • Bridges are often evident by the thinning of the road where the bridge begins and the corridor either side of the road disappears.
  • In Figure the shadows cast by the bridge is evident
  • In Figure the shadow signature indicates a change in elevation being traversed by the road which strongly indicates the presence of a bridge.
Regional Considerations:
