(a) Spectral coverage/resolution, i.e., band locations/width; (b) spectral
dimensionality: number of bands; (c) radiometric resolution:
quantisation; (d) spatial resolution/instantaneous field of view or
IFOV; and (e) temporal resolution. Table 2.2 illustrates the basic
properties of Resourcesat satellite/sensor that was used in the
present study.

The details of data processing carried out in the present study are shown in
Figure 2.4. The processing methodology involves the following major steps:
(a) Geometric correction, rectification and geo-referencing;
(b) Image enhancement;
(c) Training set selection;
(d) Signature generation and classification;
(e) Creation/overlay of vector database;
(f) Validation of classified image;
(g) Final thematic map preparation.
