| Location of Example: |
149°6'00" East, 28°46'14" 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 2.3.5.3b the SPOT imagery indicates a presence of the water with the light blue signature.
