TCEQ Air Monitoring Stations

TCEQ Air Monitoring Stations Metadata.

This layer contains TCEQ's currently active Air Quality Monitoring stations that operate at "fixed" sites. A fixed site is a station that has recorded data for over 90 consecutive days at the same location. All source data for this layer comes from the Air Quality System (AQS) database, which is maintained by the Monitoring Operations Division of TCEQ's Office of Air Quality. All air monitoring stations classified as "inactive" have been removed from the layer. For information on these older stations, please contact the Monitoring Operations Division.

Since the previous version of this layer was released in 2003, the coordinates for several air monitoring stations have been improved using GPS equipment. At this time, approximately 45% of the points (representing stations established after 1999 and reacquisition of some older ones) were acquired using GPS and the remaining 55% were obtained from manual map interpolation. The Monitoring Operations Division plans to replace these last 55% with GPS positions by the end of 2004.

Level 3 Certification - This layer does not meet the minimum 25 meter agency standard. The layer was certified with known problems that have been documented in the metadata. It is not suitable for high-precision measurement applications.

Purpose:

This layer depicts the geographic locations and selected attribute data of all TCEQ Air Quality Monitoring stations within the State of Texas. The map layer can be used to generate maps, serve as a guide to TCEQ field personnel, and be utilized to perform analysis of the dispersal of air pollutants in Texas.

Attribute_Accuracy:

Attribute_Accuracy_Report:: All attribute fields are entered by staff in the Monitoring Operations Division of TCEQ. Except for the additional fields required by the TCEQ GIS Data Review Process, all attribute fields were imported directly from the TAMIS database.

This dataset was 100% complete at time of posting.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Approximately 69% of the coordinates are based on GPS (Global Positioning System) field acquisition, however, only 27% have a confirmed accuracy of 5 meters. 12% of the stations are based on map interpolation and the remaining 18% were collected by unknown methods.

Quantitative_Horizontal_Positional_Accuracy_Assessment:

Horizontal_Positional_Accuracy_Value: 200
Horizontal_Positional_Accuracy_Explanation:: With the exception of stations marked as GPS_DIFF, the accuracies of most stations could not be confirmed based on information from the TAMIS database. Based on tests from the previous version of this layer, the estimated maximum error was no more than 200 meters. As a general rule, the coordinates for air monitoring stations established after 1999 were acquired using GPS equipment. It is uncertain whether these were all differentially corrected, therefore, for stations whose HORZ_METH field states simply "GPS", an accuracy of -9999 is given.

All coordinates and attribute information (except for the TCEQ Locational Data Standards) were imported directly from the TAMIS database.

Process_Step:

Process_Description:: All coordinates were extracted directly from the TAMIS database. All stations not within the boundary of Texas were removed. A point feature dataset was created in ArcMap using the "Add XY" utility. The minimum required GIS fields were added and populated according to the TCEQ Spatial Data Dictionary for Point data.
