Rubber Sheet Gis

Random geometric errors are corrected through a process known as rubber sheeting.

Rubbersheeting is used to make small geometric adjustments in your data usually to align features with more accurate information. Conveyor belts lacing. On the edit tab in the snapping group enable your snapping preferences. Rubbersheeting is used to make small geometric adjustments in your data usually to align features with more accurate information.

Links representing from and to locations are used to define. Rubber sheeting may improve the value of such sources and make them easier to compare to modern maps. California industrial rubber company is a family owned business with many employees having over 15 years of service and it is our vision to continue to provide excellence in service and quality in product. The input link features represent the regular links.

The source layer drawn with solid lines is adjusted to the more accurate target layer. 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. As the name implies rubber sheeting involves stretching and warping an image to georegister control points shown in the image to known control point locations on the ground.

For steps to transform features using affine or similarity transformation methods see transform features. 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. The input point features represent identity links that hold source positions unmoved during the rubbersheeting process. Features may move depending on their proximity to and length of displacement links.

Rubbersheeting is typically used to align two or more layers. Before aerial photography arrived most maps were highly inaccurate by modern standards. Rubber sheeting is commonly used after a transformation to further refine the alignment accuracy of the transformed features. Rubbersheeting makes spatial adjustments to align the input feature locations with more accurate target feature locations based on the specified rubbersheet links.

In rubbersheeting adjustments you are usually trying to align one layer with another that is often in close proximity. This process moves the features of a layer using a piecewise transformation that preserves straight lines. Use displacement links to define common locations in the source and target layers. This exercise will show you how to rubber sheet data by using displacement links multiple displacement links and identity links.
