via Nic Jefferis comes this great example of the impact of a data inaccuracy, and one that is all too uncommon!

Demolition workers relied on google maps to bring them to an address of a residential property that was to be demolished after storm damage.

The problem was that Google Maps had the location in the wrong place. The actual address was a block away. This resulted in a home being demolished, despite the owners having applied for funding to repair the storm damage it had suffered.

Yet again, the builders maxim of “Measure twice, cut once” appears to apply to a classic information quality problem.
