The Federal Communications Commission voted today to collect more accurate data about which parts of the US have broadband and which parts lack high-speed connectivity. From now on, home Internet providers will have to give the FCC geospatial maps of where they provide service instead of merely reporting which census blocks they offer service in.

The FCC's current broadband mapping system has serious limitations. The Form 477 data-collection program that requires ISPs to report census-block coverage lets an ISP count an entire census block as served even if it can serve just one home in the block. There are millions of census blocks across the US, and each one generally contains between 600 and 3,000 people.
