ABSTRACT:
Remote sensing offers watershed researchers a very different type of data from that which they have traditionally worked with. The spatial nature of remote sensing data is its most unique characteristic, especially when considering that all other hydrologic data are from point measurements. Remote sensing data give the researcher a new tool to use in scaling and in extrapolating point measurements to represent areas. In addition, remote sensing offers entirely new measurements, such as surface soil moisture, snow water content, and surface temperature, which have not been traditionally available to hydrologists.
