The georeferencing is now complete.
Qgis rubber sheeting.
Once the process finishes you will see the georeferenced layer loaded in qgis.
Esri s arcgis 8 3 has the capability of rubber sheeting vector data and arcmap 9 2 may also rubber sheet raster layers.
Qgis georeferencer plug in provides a number of transformation types including thin plate spline which enables full rubber sheeting.
Isn t an affline transformation a uniform shift.
New tutorial video on gis practical.
I believe rubber sheeting is more of a distortion based on a number of different vectors.
Qgis is a free open source gis package.
This will start the process of warping the image using the gcps and creating the target raster.
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because it treats the map as if it were made of rubber and the control points as if they were tacks pinning the historical document to a three dimensional surface like the globe.
Autocad s land desktop allows a user to rubber sheet raster data.
Qgis now has a plugin called vector bender which can spatially adjust vector data.
Back in the georeferencer window go to file start georeferencing.

For steps to transform features using affine or similarity transformation methods see transform features.
On the edit tab in the snapping group.
Rubber sheeting is commonly used after a transformation to further refine the alignment accuracy of the transformed features.
Make sure the load in qgis when done option is checked.
Before proceeding with georeferencing in quantum gis we need to activate the appropriate plugins.
