Rubber sheeting gis. 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. Before aerial photography arrived most maps were highly inaccurate by modern standards. The input point features represent identity links that hold source positions unmoved during the rubbersheeting process. For steps to transform features using affine or similarity transformation methods see transform features.
This process moves the features of a layer using a piecewise transformation that preserves straight lines. Rubbersheeting makes spatial adjustments to align the input feature locations with more accurate target feature locations based on the specified rubbersheet links. Rubber sheeting is commonly used after a transformation to further refine the alignment accuracy of the transformed features. Rubbersheeting is used to make small geometric adjustments in your data usually to align features with more accurate information.
Rubbersheeting is typically used to align two or more layers. 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. Skip to main content. Rubbersheeting is used to make small geometric adjustments in your data usually to align features with more accurate information.
In rubbersheeting adjustments you are usually trying to align one layer with another that is often in close proximity. Features may move depending on their proximity to and length of displacement links. The input link features represent the regular links. Rubber sheeting may improve the value of such sources and make them easier to compare to modern maps.
The source layer drawn with solid lines is adjusted to the more accurate target layer. Toggle navigation ngs home. This exercise will show you how to rubber sheet data by using displacement links multiple displacement links and identity links. Rubber sheeting a procedure for adjusting the coordinate s of all the data points in a dataset to allow a more accurate match between known locations and a few data points within the dataset.
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.
