Choosing a rubbersheet method

Rubbersheeting is used to make small geometric adjustments in your data usually to align features with more accurate information. Use displacement links to define common locations in the source and target layers. Features may move depending on their proximity to and length of displacement links. The farther features are away from displacement links, the less they will move. Identity links can be used to help hold features in certain locations. Additionally, a rubbersheet can be confined to a polygonal area.

Two rubbersheeting options are supported: natural neighbor and linear. These determine how the underlying rubbersheet surface is created during the adjustment. The linear option will be slightly faster and produces good results when you have many links spread uniformly over the data you are adjusting. Natural neighbor should be used when you have few links spaced widely apart.

Steps:

1. Click the Spatial Adjustment menu, point to Adjustment methods, then click a transformation method.
2. Click the Spatial Adjustment menu and click Options.
3. Click the Adjustment methods drop-down arrow and click Rubbersheet.
4. Click the Options button.
5. Click either the Natural Neighbor or Linear method and click OK.
6. Click OK to close the Adjustment Properties dialog box.
