Get the data
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 land grid: original patent survey lines and tracts, county by county. Texas is not on the Public Land Survey System, so this abstract and survey grid is the only way to place a legal description.
What you can do with it
Locate an abstract and survey on a map, which is how Texas leases and permits describe position.
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.
