digitized from a historical map of low accuracy. The mathematics and procedure are very similar to the
georeferencing Georeferencing means that the internal coordinate system of a map or aerial photo image can be related to a geographic coordinate system. The relevant coordinate transforms are typically stored within the image file ( GeoPDF and GeoTIFF are exam ...

Applications in history and historical geography
Rubbersheeting is a useful technique in
HGIS, where it is used to digitize and add old maps as feature layers in a modern
GIS. Before aerial photography arrived, most maps were highly inaccurate by modern standards. Rubbersheeting may improve the value of such sources and make them easier to compare to modern maps.
