Introduction

There can be almost endless applications of remote sensingtechniques for monitoring and management of land surface, seasurface, and atmospheric features and processes.

Each application itself has specific demands, for sensor (optical,thermal, microwave), spectral resolution, spatial resolution, andtemporal resolution.

With the availability of very high spatial resolution satellites in therecent years, the applications have been multiplied.
