Summary: One of the best definitions I have found for data fusion
Keywords: ##zettel #data #fusion #definition #archive
Defined as the use of multiple technologies or location systems simultaneously to form hierarchical and overlapping levels of sensing, sensor fusion can provide aggregate properties unavailable when using location systems individually
This definition of data fusion comes from Hightower & Borriello  and I think it provides a very good explanation of what data fusion actually is. I decided to generalize it as their definition only concerns with location systems – here is my paraphrase:
When one utilizes differing technologies to form tiers of improving sensor accuracy; this methodology can compensate for the loss or absence of signal from other sensors by providing multiple overlaps for the same defining properties of a system.
