What is remote sensing? The International Society for Photogrammetry and Remote Sensing (ISPRS) defined Remote Sensing (RS) as: “The art, science, and technology of obtaining reliable information about physical objects and the environment, through the process of recording, measuring, and interpreting imagery and digital representation of energy patterns derived from non contact sensor system ". This definition considered photogrammetry as sub-field of remote sensing –via cameras recording on film, which may then be scanned (aerial photos) –via sensors, which directly output digital data (satellite imagery)

History of remote sensing 1783: The Marquis d’Arlandes and Pilatre made a voyage near Paris using a balloon. Photography using balloon, pigeon 1860: Aerial photos in Russia and the USA : The first World War and the second World War ( ) had seen tremendous development in photography 1927: Robert Goddard launched the first liquid-fueled rocket. 1955: Work began on the Baikonur launch site in central Asia. 1957: Sputnik 1 launched from Baikonur (first satellite) 1961: Yuri Gagarin launched in the Vostok 1 capsule, becoming the first human in space. 1969: Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon. 1971: The first Space Station in history, the Russian Salyut : (US Landsat1) the concept of imaging from satellites is introduced 1986: France launched the first stereo-image satellite (SPOT1) 1992: The space year (the maturity of remote sensing - 20 years of operation) 1995 The Shuttle-Mir Program (1 st phase of the International Space Station (ISS) The first 3 astronauts (2 Russian and one American) start to live in the ISS

Remote sensing basic processes

Advantages of remote sensing Provides a regional view (large areas) Provides repetitive looks at the same area Remote sensors "see" over a broader portion of the spectrum than the human eye Sensors can focus in on a very specific bandwidth in an image or a number of bandwidths simultaneously Provides geo-referenced, digital, data Some remote sensors operate in all seasons, at night, and in bad weather

Remote sensing applications Land-use mapping Forest and agriculture applications Telecommunication planning Environmental applications Hydrology and coastal mapping Urban planning Emergencies and Hazards Global change and Meteorology
