The process of georeferencing varies slightly based on the GIS software you are using and the characteristics of the raster data you are working with. The georeferencing process may also be combined with the process of clipping raster data to remove unwanted portions of a scanned image and with the process of image compression to reduce the raster file size. This georeferencing process is typically carried out using GIS software like QGIS, ArcMap, or ArcGIS Pro and is a powerful way to add value to scanned images of paper maps, printed aerial photos, and other geospatial raster data that is missing coordinate information by preparing the data for GIS based analysis and digitizing operations.
