Spatial data layers and conflation September 18, 2007

Conflation is more than matching features from different spatial sources.  A good spatial-matching technology that includes conflation as a parameter should also be defined by location, the shapes attributes, and its relationships to other objects. 

A good example of this is when two or more road networks have conflicting views – how do you proceed, if you end up only wanting to display one of the sources? 

What geometrical matching techniques or advice do you have on this topic?
