The identification of features is provided by the distinct electromagnetic energy it emits,reflects, or otherwise transmits. This is called the spectral signature. Other signatures such as tone (lightness or darkness), texture (surface roughness or smoothness), pattern,shadow, shape, and size are as important. Thus, through the use of the thematic mapper sensor, such elements as water features, soils, and vegetation can be identified and distinguished from each other.
Are there legal restrictions on access or use of the data?
