Land questions in Brewster County start in the same place: the official parcel map. Here's how to use the Brewster County GIS map to find owners, acreage and boundary lines, and where it falls short.
We'll cover the official map, the communities and terrain around Alpine, how property lines work in Texas, and where the deeds come from.
Getting into the Brewster CAD interactive map
The Brewster CAD interactive map is the county's own public parcel viewer; it runs on a BIS Consulting map viewer. Rural tracts near Marathon often show an abstract number in the legal description; note it along with the property ID. We keep the link current on our Brewster County (TX) directory page, next to the neighboring maps.
Who needs this map
The same map serves very different jobs around Alpine.
- If you hunt the country around Altuda, the owner layer tells you who to ask and where the next property begins.
- Small-farm and homestead buyers looking around Altuda compare tract sizes and shapes on the map before calling a listing agent.
- A buyer comparing houses in Study Butte and Marathon can line up the lot sizes side by side before booking showings.
- Heirs sorting out family land near Marathon use the record to confirm acreage and the legal description.
The lay of the land in Brewster County
The county seat is Alpine, home to the courthouse. The county was organized in 1887 and named for Henry Percy Brewster, so some tracts carry a long chain of deeds. About 9,513 people lived in Brewster County in 2023, according to Census Bureau estimates, on roughly 6,184 square miles. Sparse settlement means wide parcels. Outside Alpine the county map reads as a quilt of large holdings with long gaps between houses. Water features such as the Rio Grande Wild and Scenic River shape where lots fall and where floodplain sits. Public ground such as Big Bend National Park appears as large unbroken blocks, and the private parcels around it draw hunters and recreation buyers.
Work and land use in Brewster County
In the 2022 County Business Patterns data, Brewster County had 290 establishments; accommodation and food services, retail trade, and other services led the count. The sectors that stand out against the national mix are accommodation (hotels, motels, RV parks and camps), utilities, and heavy and civil engineering construction. Visitor spending across the county tends to support demand for small getaway parcels, including lots near Marathon. Keep that in mind when you compare parcels in Brewster County: who works here shapes what land sells.
Reading property lines on the Brewster County GIS map
Parcel boundaries on the Brewster County viewer are drawn to keep tax accounts straight, so small offsets from the true line are expected. Around Marathon, a rural legal description will cite an original survey and abstract; match it to the lines on the map. If a neighbor's fence near Marathon and the map disagree, neither one is proof. A survey is.
Private and public hunting ground in Brewster County
Most hunting ground in Brewster County is privately owned, and the parcel map is how you find out whose it is. Hunters headed to Big Bend National Park should check where the public boundary ends; the tracts beyond it are private. The Texas Parks and Wildlife Department handles licenses, seasons and public-land maps for Brewster County. Ask owners near Study Butte early, ask politely, and send a thank-you after the season.
Where Brewster County deeds and plats are kept
The appraisal district handles assessments, while recorded deeds and plats for Brewster County are kept by the county's land records office. For a tract near Marathon, the appraised value is set by the Brewster County appraisal district, which Texas law keeps separate from county government. Easements and rights-of-way are usually in recorded documents, not on the parcel map, so read the deed itself for a tract near Altuda.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
