Sources and methodology

How we collect, describe and correct the records on this map.

Sources

Our map combines community-contributed OpenStreetMap records with selected public agency and other documented sources. Each mapped record links to its source. Source dates and the date we checked a source can differ; neither alone proves when a camera was installed or whether it operates today. The sources and limitations page provides more detail.

Verification and limits

We preserve the location and attributes supported by a source and mark uncertainty where appropriate. A mapped source record is not necessarily one physical camera. Coverage is incomplete, locations may be approximate and records can be outdated. A source name or camera type does not by itself establish who operates a device or what it records.

Corrections and missing cameras

Use the camera report form for a missing or incorrect map record, or the contact form for other corrections. A submission enters a review queue and does not automatically add a map point. Include a public record or an OpenStreetMap edit that supports the correction when available.

Use and attribution

OpenStreetMap data is available under the Open Database License; credit OpenStreetMap contributors. Other sources have their own terms. A map appearance does not establish a blanket right to redistribute every source.
