Change Detection

Change detection is a method used in remote sensing and GIS to identify changes in an area of interest over time. It is used for a variety of applications, such as monitoring land cover and land use change, detecting alterations to natural resources, and identifying environmental changes. By analyzing multiple images of an area from various times, change detection techniques are able to detect differences in features between the images and provide an estimate of the amount of change that has taken place in that area. This information can be used for a variety of purposes, such as land management, resource management, and even urban planning. Change detection methods are also important for scientific studies, such as assessing the success of conservation efforts or understanding the impacts of climate change.
