See 40 CFR, Chapter I Section 81, et seq. The library layer is a polygon feature class that shows the district boundaries, as of March 1998, and gives their names. Air districts are large areas that incorporate multiple counties or parts of counties and, in some cases, more than one air basin (see 'AIRBASINS' layer). Their definitions are based on county lines for the most part. There are 41 districts in California.ADIS polygons represent California federal air districts.Teale Data Center GIS LabUnknownadisadisvector digital datahttp://www.dot.ca.gov/hq/tsip/gis/datalibrary/gisdatalibrary.htmlpublication date19920901199503011997030119980301-124.409596-114.13147342.00983532.534028-124.409596-114.13147332.53402842.009835ShapefileTeale Data Center GIS Lab Caltrans TSI/GIS Data Branch Metadata Coordinator mailing and physical address Sacramento CA 95814

The county lines were digitized from 1:100,000 source material so the accuracy of the linework is inherited from that layer.
