Details on how thermal data is processed and used in these various applications is beyond the scope of this article.
Numerous references can be found in literature for the use of thermal data for most of these applications. A modest
collection of these reference sources is also available at http://www.itc.nl/-prakash/research/thermal ref.html
5 CONCLUSIONS
From the issues addressed in section 3 of this article, some limitations of thermal remote sensing are clear. On the other
hand, from the variety of possible applications highlighted in section 4, the advantages and potentials of thermal remote
sensing are also obvious. One more fact that is now clear is that new satellite and airborne platforms with new and
improved thermal sensors also promise to bring more interest and challenge in this relatively less explored field.
Therefore, now there is a definite need to promote the understanding and the use of thermal data by the scientific and
application community. These developments should encompass among other things
e fundamental research in the principles of thermal remote sensing
e laboratory measurements of spectral response of natural materials in the thermal infrared region
e development of more sophisticated sensor technology
finally to application oriented research where the already explored application fields can be refined and new
application areas can be tapped.
One of the most promising way to ensure that such a goal is achieved in by introducing the topic of thermal remote
sensing in greater depth in the remote sensing educational programmes. The 'spin off ' effect of such a venture would be
that more and more researchers with fresh ideas would explore the thermal data and its possibilities.
