Autocad s land desktop allows a user to rubber sheet raster data.
Raster rubber sheeting.
If there is only one image in the current drawing that image is automatically selected.
In cartography rubbersheeting refers to the process by which a layer is distorted to allow it to be seamlessly joined to an adjacent geographic layer of matching imagery such as satellite imagery most commonly vector cartographic data which are digital maps.
Select the image to rubbersheet.

This exercise will show you how to rubber sheet data by using displacement links multiple displacement links and identity links.
The autocad raster design toolset helps you convert raster images into dwg objects with its powerful vectorization tools.
Linear this method creates a quick tin surface but does not really take into account the neighborhood.
The method parameter determines the interpolation method used to create the temporary tins in rubbersheeting.
It includes the process known as rubber sheeting which involves stretching and warping image to georegister using control points shown in the image and known control points on the ground called ground control point gcp.
This is sometimes referred to as image to vector conflation.
Conflation applications use rubbersheeting to align layers in preparation for transferring attributes.
Instead it tries to rectify feature locations within a single raster image.
It is slightly faster and produces good results when you have many rubbersheet links spread uniformly over the data.
Software for rubber sheeting esri s arcgis 8 3 has the capability of rubber sheeting vector data and arcmap 9 2 may also rubber sheet raster layers.
This process moves the features of a layer using a piecewise transformation that preserves straight lines.
Rubbersheeting is commonly used after a transformation to further refine the accuracy of the features to an existing layer or raster dataset.
See about spatial adjustment rubbersheeting for more details.
Where applicable you can see country specific product information offers and pricing.
Raster entities will not be truly rubber sheeted they will be aligned and sometimes diagonally stretched.
However this may be sufficient in some cases.
