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.
Gis rubber sheeting.
Use displacement links to define common locations in the source and target layers.
Before aerial photography arrived most maps were highly inaccurate by modern standards.
Features may move depending on their proximity to and length of displacement links.
Rubbersheeting makes spatial adjustments to align the input feature locations with more accurate target feature locations based on the specified rubbersheet links.
The input link features represent the regular links.
Rubbersheeting is used to make small geometric adjustments in your data usually to align features with more accurate information.

Conveyor belts lacing.
The method of registering one layer of digital data to another by using a set of common points rather than by coordinates of control points.
Rubbersheeting is used to make small geometric adjustments in your data usually to align features with more accurate information.
The source layer drawn with solid lines is adjusted to the more accurate target layer.
Rubber sheeting may improve the value of such sources and make them easier to compare to modern maps.
This exercise will show you how to rubber sheet data by using displacement links multiple displacement links and identity links.
The input point features represent identity links that hold source positions unmoved during the rubbersheeting process.
In rubbersheeting adjustments you are usually trying to align one layer with another that is often in close proximity.

Grade and commercial lines of sheet rubber are available in durometers hardness grades from 10 90 durometer and thicknesses from 015 to 1 00.
This process moves the features of a layer using a piecewise transformation that preserves straight lines.
The source layer drawn with solid lines is adjusted to the more accurate target layer.
