Automatic georeferencing (AGR) is the process of automatically determining the spatial coordinates of a digital image or dataset and placing it onto a specific geographic location on a map. This process involves comparing features or points in the image with known geographic locations or reference data, and then using mathematical algorithms to estimate the spatial location of the image.
Automatic georeferencing is often used in Geographic Information Systems (GIS) to create accurate maps and to integrate different types of data from various sources. It is also used in fields such as remote sensing, surveying, and cartography, where precise spatial information is essential. The use of automatic georeferencing tools can save time and resources compared to manual georeferencing, especially when dealing with large datasets or multiple images.
