Gis Rubber Sheeting
Rubber sheeting a procedure to adjust the features of a coverage in a nonuniform manner.
Gis rubber sheeting. The method parameter determines the interpolation method used to create the temporary tins in rubbersheeting. It is slightly faster and produces good results when you have many rubbersheet links spread uniformly over the data. Spatial adjustment rubbersheeting makes small geometric adjustments in your data usually to align features with more accurate information. For steps to transform features using affine or similarity transformation methods see transform features.
Rubber sheeting is necessary because the imagery and the vector data will rarely match up correctly due to various reasons such as the angle at which the image was taken the curvature of the surface of the earth minor movements in the imaging platform such as a satellite or aircraft and other errors in the imagery. Rubber sheeting may improve the value of such sources and make them easier to compare to modern maps. Rubber sheeting a procedure for adjusting the coordinates of all the data points in a dataset to allow a more accurate match between. 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. Rubber sheeting is a technique for edge matching and is another name for warping. See about spatial adjustment rubbersheeting for more details. Rubber sheeting is commonly used after a transformation to further refine the alignment accuracy of the transformed features.
