Earth observation is the gathering of information about planet
Earth’s physical, chemical and biological systems via
remote sensing technologies supplemented by earth surveying techniques, encompassing the collection, analysis and presentation of data. Earth observation is used to monitor and assess the status of, and changes in, the
natural environment and the
built environment. In recent years, Earth observation has become technologically increasingly sophisticated. It has also become more important due to the dramatic impact that modern human civilization is having on the planet
Earth, and the need to minimize negative impacts along with the opportunities Earth observation provides to improve social and economic well-being.
