Multitemporal Imaging

Multitemporal imaging is the acquisition of remotely sensed data from more than one time period. Acquiring multiple views of natural or built features through time provides an enhanced ability to accurately identify these features, significant information about how our world is changing, and unique insight into the relationships between the environment and the impact of human activities. Multitemporal images and analysis techniques provide the tools to monitor land use and land cover change (LUCC) and have been instrumental in providing an understanding of global environmental change. Our understanding of the impacts of global change would not have been possible without multitemporal imaging of diverse phenomena such as snow and ice extent, sea surface temperature, deforestation, drought, water resources, wildfire, desertification, and more.
