Welcome to the California Air Resources Board's Enforcement Data Visualization System (EDVS). In order to help the general public better understand CARB's enforcement efforts, to provide community members a user-friendly way to access CARB enforcement information, and to facilitate the development of community emissions reduction programs, CARB's Enforcement Division developed EDVS for users to visualize CARB's enforcement activities across the state, including field inspections and case settlements, on a map interface.
EDVS includes enforcement statistics from activities performed by CARB as well as activities performed by air districts on behalf of CARB. EDVS includes all CARB inspection data; however, it may not include all inspection data from air districts. Data in EDVS is updated annually.

Markers and Marker Clusters
The application utilizes dynamic marker clustering techniques to enhance user experiences when displaying a large amount of data. Single markers (markers in solid blue) represent one single location, and marker clusters (markers with halos) represent a group of neaby markers. Left-click on a marker or marker cluster will bring up the statistics panel; right-click on a marker cluster will expand it and set the map view accordingly.
