MapQuest Maps License Plate Readers, a Layer Google Maps Lacks

MapQuest, the long-running mapping service, has added a feature that Google Maps does not offer: a map of automated license plate reader cameras. The reported detail is limited to that headline comparison, so it is unclear from the available information how the locations were gathered, how complete the layer is, or how often it is updated.

License plate readers are cameras that photograph vehicles and convert plate numbers into searchable records. Police departments use them widely, and many are operated by private companies that share data with law enforcement. Their placement is often publicized only in part, which is why a map of their locations draws attention from drivers and privacy advocates alike.

For drivers, the feature offers a way to see camera locations before they pass them. For critics of the technology, a consumer map making those sites easy to find raises a different question, namely whether public access to camera placement helps people avoid monitored areas or simply increases awareness of how widespread the systems have become. Neither argument is settled by the feature itself.

Google Maps has not been reported as adding a similar layer. Readers who want to verify the feature, its data sources, or its coverage area should check MapQuest's own description of it, which the source material does not reproduce.
