Rubber sheeting is a useful technique in historical gis where it is used to digitize and add old maps as feature layers in a modern gis.

Qgis has a lot of documentation.
Rubber sheeting may improve the value of such sources and make them easier to compare to modern maps.
Or qgis or anything free.
Qgis georeferencer plug in provides a number of transformation types including thin plate spline which enables full rubber sheeting.
Rubber sheeting is commonly used after a transformation to further refine the alignment accuracy of the transformed features.
For steps to transform features using affine or similarity transformation methods see transform features.
Qgis is a free open source gis package.

The source layer drawn with solid lines is adjusted to the more accurate target layer.
In rubbersheeting adjustments you are usually trying to align one layer with another that is often in close proximity.
Help center detailed answers to any questions you might have.
Once the process finishes you will see the georeferenced layer loaded in qgis.
This will start the process of warping the image using the gcps and creating the target raster.
Before aerial photography arrived most maps were highly inaccurate by modern standards.
Rubbersheeting is used to make small geometric adjustments in your data usually to align features with more accurate information.
Back in the georeferencer window go to file start georeferencing.
Make sure the load in qgis when done option is checked.
In cartography this is known as rubber sheeting because it treats the map as if it were made of rubber and the control points as if they were tacks pinning the historical document to a three dimensional surface like the globe.
