Remote sensing is the art and science of detecting information about an object, area or phenomenon without making physical contact with it.
The process can be done by capturing images from satellites, aerial photography, sonar system… The main uses of remotely sensed images are related to studying and analyzing the complex water resources systems.
Three quarters of the Earth’s surface is covered with water, mainly in oceans and seas (97.5% of world’s water supply), rivers, lakes, snow & glaciers (only 2.5% of world’s water). Remote sensing techniques and Earth observation data are used to understand the dynamics of many important resources like ground water, water quantity, water chemistry, climate change, surface water… using mapping tools.
