  • Generally there are a lack of access points, buildings and infrastructure along the railway line.
  • In Figure: 2.2.5.1a the colour of the railway line is similar to the surrounding area, due to the lack of pavement.
  • In Figure: 2.2.5.1b the spectral signature of the railway (red) is similar to the surrounding vegetation and landscape, as opposed to the road which stands out as bright blue.
