This is a Vector data set. It contains the following vector data types (SDTS terminology):
The map projection used is Lambert Conformal Conic.
Planar coordinates are encoded using coordinate pair
Abscissae (x-coordinates) are specified to the nearest 0.000100
Ordinates (y-coordinates) are specified to the nearest 0.000100
Planar coordinates are specified in meters
The horizontal datum used is D_GRS_1980.
The ellipsoid used is Geodetic Reference System 80.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257222.
Coordinates defining the features.
Sequential unique whole numbers that are automatically generated.

This data set was developed for use by Water Rights Permitting and Availability Section staff and outside users as reference for basic permit information such as a current owner or water rights in a particular county. Detailed information beyond this basic data may need to be researched in the file records.
, Permit Records.
When a water use permit is granted by the TCEQ one or more rows of data are created for the water right in the database.

There is a QA/QC (Quality Assurance/Quality Control) process that has been in place for data entry since 1991. Data entered prior to this date has not been extensively QA/QC'd. Note that structural limitations in the current database have limited the way information is displayed. For example, permits that have more than one county authorization may have only one shown.
For geo referencing, latitude and longitude information is available. This is digitized information and is subject to digitization error. There are currently no resources to verify the locational information on the ground.
The Water Rights Permitting and Availability Section is currently involved in scoping and analysis for redesign (normalization) of the database and the associated water use tables as well as the watermaster operations. In the redesign process the database will capture more permit information as well as have a structure to support displaying this information. This process is ongoing and will continue for the next several months.
The database contains permit information from authorizations to use water that have come down to the TCEQ through predecessor agencies from the late 1800's. The basis for this determination is review of the permit file and its associated priority date which establishes its position relative to other water rights' authorizations to divert water in time.
