Location of Example: |
144°5'7" East, 35°1'15" South |
Distinctive Characteristics: |
- Dams can be differentiated from vegetation on thematic imagery by their blue signature compared with the red signature of the vegetation.
- Dams can also be identified by the surrounding earth which was disturbed or displaced during the construction of the Dam. This can aid in distinguishing dry dams from depressions.
- Spectral response may also indicate the presence of water even in a dry dam. In Figure 2.3.5.1 the SPOT imagery indicates a presence of the water with the light/royal blue signature.
