This dataset was created by the Transportation Planning and Programming (TPP) Division of the Texas Department of Transportation (TxDOT) for planning and asset inventory purposes, as well as for visualization and general mapping. County boundaries were digitized by TxDOT using USGS quad maps, and converted to line features using the Feature to Line tool.

FEMA Framework Basemap datasets comprise six of the seven FGDC themes of geospatial data that are used by most GIS applications (Note: the seventh framework theme, orthographic imagery, is packaged in a separate NFIP Metadata Profile): cadastral, geodetic control, governmental unit, transportation, general structures, hydrography (water areas & lines. These data include an encoding of the geographic extent of the features and a minimal number of attributes needed to identify and describe the features. (Source: Circular A16, p. 13). Base Map data includes features for USGS Quad Index Lines (BASE1); NGS Bench Marks (BASE2); FEMA DFIRM Roads, Streams, and Lakes (BASE3); City of Dallas Corporate Limits and Roads (BASE4)

The geographic extent of a County, this file represents 3 counties (Dallas, Collin, Denton) clipped from a statewide 2010 Census dataset that are in the Tx N. Central 4202 State Plane projection. The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The primary legal divisions of most States are termed counties. The 2010 Census boundaries for counties and equivalent entities are as of January 1, 2010, primarily as reported through the Census Bureau's Boundary and Annexation Survey (BAS).Metadata edited 01/2021

Description: These layers contains the nonattainment and maintenance areas (counties) in Texas. It was derived from the EPA’s Greenbook. A nonattainment designation means an area has not achieved compliance with the National Ambient Air Quality Standards (NAAQS). A maintenance designation means the area was formerly in nonattainment but has monitored attainment and is currently under a maintenance plan1. The U.S. Environmental Protection Agency (EPA) established the 8-Hour ozone NAAQS in 1997 and revised it with the 2008 and 2015 standards. The 1997 ozone NAAQS was revoked in April 6, 20152, along with the classifications, so the current maintenance designation is based on the approval of a maintenance plan by EPA for the region; rather than an official reclassification. These nonattainment counties were designated by the EPA based on their air quality monitoring data. Before it was revoked, there were 17 nonattainment counties for the 1997 ozone NAAQS: 8 counties in the Houston/ Galveston area (Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller); and 9 counties is the Dallas/Fort Worth area (Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, and Tarrant). There are 3 maintenance counties for the 1997 ozone NAAQS in the Beaumont/Port Arthur area (Hardin, Orange, Jefferson)3. There are 18 nonattainment counties for the 2008 ozone NAAQS: 8 counties in the Houston/ Galveston area (Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller); and 10 counties in the Dallas/Fort Worth area (Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, Tarrant, and Wise)4. There are 16 nonattainment counties for the 2015 ozone NAAQS: 1 county in the San Antonio area (Bexar); 6 counties in the Houston/ Galveston area (Brazoria, Chamber, Fort Bend, Galveston, Harris, and Montgomery); and 9 in the Dallas/Fort Worth area (Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Tarrant, and Wise)5. The EPA established the NAAQS for particulate matter with a diameter of 10 micrometers or smaller (PM-10) in 1987. There is one nonattainment area for the 1987 PM-10 NAAQS: which is a portion of El Paso county6. The EPA established the NAAQS for carbon monoxide (CO) in 1971. There is one maintenance area for the 1971 CO NAAQS: which is a portion of El Paso county7. References:1.
