No download is available for this dataset yet. It is catalogued here so the record layout and code lookups are at least written down.
What this is
The base map RRC draws its own products over: roads, hydrography, municipalities and political boundaries, county by county.
What you can do with it
Reproduce the Commission's own map look, or provide context for a well map without a third-party basemap.
Gotchas
Every RRC map layer is published in the Geographic coordinate system in decimal degrees on the NAD27 datum — EPSG:4267. That is not what web mapping expects. Overlaying it on anything modern without reprojecting to WGS 84 puts Texas wells roughly 100 metres from where they belong.
Files are packaged county by county under RRC's 8.3 naming convention, so a statewide layer means merging 254 shapefiles.
EZRRC does not parse this file. Upstream has not built a reader for it yet, so the catalog documents it and links to the Commission's own copy rather than pretending to serve rows it does not have.
