Steve Lewis: Taking fewer wrongs turn with a national address database

If your GPS has ever made you take a wrong turn, you know having a proper address is important. But currently, federal, state, local and private organizations collect that information individually. No national, authorized registry of addresses even exists. That's why the Transportation Department wants to build it — a single, unified national database of addresses. Steve Lewis is the department's chief geospatial information officer. He joined Tom Temin on the Federal Drive with more on the project.
