Remote sensing is the collection and analysis of scientific data about phenomena at, above or below the earth’s surface without coming into physical contact with them. There are many ways of collecting such data, for example by using conventional aerial photography, radar and airborne electronic scanning devices. Satellites have also gained a prominent position in this field. Remote sensing techniques and the images they produce are playing an increasingly important role in meeting many of mankind’s complex and often disturbing challenges, such as climate change, population growth, food, water and energy security, health and land and housing needs.
The potential of remote sensing is huge. And the huge quantities of data produced by these techniques pose yet another challenge. This is where the geographical information systems (GIS) come in. Central to every GIS is the database, which stores the data on which the eventual output depends. Designing software to apply these data to real-world problems is another part of the game. Software gives users access to the database and transforms and manipulates the data for such purposes as studying trend patterns, examining environmental issues and simulating the outcomes of project proposals or planning procedures. Throughout our programmes at ITC, we cover the full range of disciplines involved in this field. Studying at ITC will equip you to take your place in the field of international development.
