Spatial data layers and conflation September 18, 2007

Posted by Peter Benza in Data Accuracy, Data Elements, Data Formats, Data Types, Data Visualization.

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?
