Source and coverage
These guides count Flock-tagged and other ALPR source points, excluding other surveillance layers. County-equivalent areas keep the names in the map outlines. Counties with fewer than five mapped plate readers are omitted unless a sourced agency record makes a guide useful. Missing locations are expected.
