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.
webHow to Use
Click on the "Options" button to bring up the panel for the main menu, where users can select region, map type, program, year, and category etc. Users can also turn on or off the markers and heatmap layer.
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.
Specify a Custom Region
Users can draw a custom region on the map in addition to selecting from the available pre-defined regions. Click the shape icons at the top-right corner of the map to start drawing a polygon or a circle. Custom drawings can be deleted or modifed.
Navigate to a Location
Click the search icon at the top-left corner of the map and enter an address, city or zipcode, then press Enter to confirm where to navigate to. Click on the "Around Me" button to make the system try to locate a user automatically (browser support needed).
Recenter Map View
Click on the "Recenter" button to bring the map view back to the original postion.
announcementAbout the Data
Data included in this application comes from CARB's internal enforcement databases. For data points with no reliable location information, some were assigned approximate locations, and some were omitted. However, the percentage of data without reliable location information is very low and does not affect the general accuracy and representativeness of the data. The data will be updated annually.
