Imagine having a treasure map without any coordinates! That's what a scanned map is like in GIS - it contains valuable information, but it's missing the key to locating it in the real world.
Georeferencing, within the realm of GIS, involves linking a scanned or paper map to real-world geographic coordinates. When a paper map undergoes scanning or digitization, it transforms into a raster image devoid of geographic coordinates. Georeferencing primarily aims to precisely align the map image with a spatial reference system. By georeferencing scanned maps, GIS users gain the ability to digitize data directly from digital copies, allowing them to capture geographic coordinates during the process.
