Background Information

ARB works closely with local air districts to update and to improve the emission inventory of criteria and toxic air pollutants from point sources and certain areawide sources. The California Emission Inventory Development And Reporting System (CEIDARS) is a relational database hosting the source information and utility information of the emission inventory. For point source emissions, the accurate location information of emission facilities is critical to many ARB programs, such as GIS-based emission inventory, air pollution monitoring, air quality modeling, and the health risk assessment at local and community levels.

Air districts report facility location using various geographic coordinate systems, map projections and datums. To promote consistency and usability of the spatial data in CEIDARS, ARB staff converted facility location data into longitude and latitude under the NAD83/WGS84 datum whenever feasible. For facilities without geo-coordinates, ARB staff populated the longitude and latitude using geocoding methods based on the facility address. In cases where the facility address was not available, the centroid of the facility’s zip code, county or air district was assigned as the facility location. Inaccuracies and errors exist in the spatial data of CEIDARS. A systematic QA/QC check on facility location is both necessary and greatly simplified with the Facility Locator online tool.

About Facility Locator

Facility Locator is a web-based tool to help air district staff QA facility location data in CEIDARS. It offers an easy way to query, sort, and search facilities in CEIDARS, and to locate the facilities on Google Maps based on their geo-coordinates and street addresses. Facility Locator provides a number of options and measures to QA the facility location data, including built-in geocoder, point-and-click geo-coordinates generator, business search engine, and interactive maps of California air basins, air districts and counties. Facility Locator leverages functionalities of Google Maps, and deploys various overlays and controls of Google Maps, such as base maps, satellite images, and elevation terrains.

Step 6. Click on the ‘map’ link of a facility record to locate the facility on Google Maps.

The red balloon marker(iconr) is based the geo-coordinates of the facility, and the blue push-pin marker(blue-pushpin) is based its street address. If these two markers are far apart from each other, then at least one of them might be wrong. The map scale bar on the lower-left corner can be used as a reference to estimate the distance between these two markers. If the geocoding process failed due to the incomplete or incorrect facility address, find the correct facility address and go to Step 7.
