Abstract

Remote sensing is the operation of sensing remote pictures of the Earth. Geographical information system (GIS) is a system through which geographical informations can be retrieved. Hydrologic science now uses both the techniques in various methodologies to reduce the amount of field work and problems regarding data scarcity. From catchment delineation to identification of hydrologically similar units, GIS and remote sensing are used very frequently and with greater accuracy. The present note gives a simple, introductory overview of both the techniques along with their application methodology for water science, especially in river hydrology.

The authors would like to state that the above article is only for education purpose. The concepts are well discussed in different literatures. The reason for addition was merely to educate readers about concepts involving remote sensing and GIS which may help them to understand the research papers (Chapter 1-20) at a greater clarity.
