The application of remote sensing techniques to hydrology has attracted the interest of engineers and scientists since the launch of weather satellites. More recently, the high Quality and quantity of data from the ERTS-1 (now LANDSAT-l) and LANDSAT-2 satellites has heightened that interest. After several years of experience, the significant advantages of digital signal processing techniques have become apparent to most users and for most applications.
In this paper we survey briefly the advantages of digital techniques in the applications of remote sensing to hydrology. We illustrate these advantages by examples of data correction, pseudocolor information display, multiband data combination and information extraction. These techniques have been applied to LANDSAT-1 and NOAA-3 VHRR data.
