Convert Texas Abstract to GPS Coordinates | TXSS Conversion Guide

Quick Answer: Paste a Texas legal description (e.g., A-123 Reeves County, TX) into Township America and get latitude, longitude, polygon boundaries, and acreage in one click. Free to use, no Texas mode toggle, no separate workflow.

Texas legal descriptions don't look like PLSS descriptions, but converting them is just as fast. This guide walks through every TXSS shape Township America accepts, plus batch and API workflows.

Supported Input Formats

Township America's parser is tolerant of abbreviation, case, and punctuation. The three primary shapes:

Format 1: Abstract-Only

The simplest form — abstract number plus county:

A-123 Reeves County, TX
Abstract 250, Bowie County
Abs 47 Pecos County

You can use A-, Abstract, Abs, or Abst — all are accepted. The county is required to disambiguate abstracts with the same number across different counties.

Format 2: Block & Section

Common in West Texas oil and gas country:

Block 5, Sec 14, T&P Survey, Reeves County
Blk 13 Sec 9 H&TC Survey, Loving County
Block 5, T&P RR Co. Survey, Section 14, Reeves

If a block number exists in multiple railroad surveys in the same county, you need the survey name. Block 5 in Reeves County is one parcel under T&P and a different one under GC&SF — the parser will ask which you mean.

Format 3: Survey-Name

For Spanish/Mexican leagues, labors, and original land grants in South and Central Texas:

John Smith Survey, Bexar County
W. H. Jenkins Survey, Karnes County
Maria de los Reyes Survey, Cameron County

Common Conversion Examples

Example 1: Permian Basin Lease

Input: Block 5, Sec 14, T&P Survey, Reeves County

Result: A ~640-acre section in the Texas and Pacific Railway Company Survey, returned with a polygon and centroid near 31.4128°N, 103.8721°W.

Example 2: East Texas Pine

Input: A-250 Bowie County, TX

Result: An East Texas abstract — typically smaller and often irregular due to early-1800s metes-and-bounds origin.

Example 3: South Texas Ranch

Input: John Smith Survey, Bexar County

Result: A ~4,400-acre Spanish league grant — a single named survey polygon, returned with centroid and boundary.

Example 4: Section-Level Lookup

Texas TXSS doesn't use standardized PLSS-style quarter sections, but section-level lookups within Block & Section descriptions work:

Block 5, Sec 14, T&P Survey, Reeves

returns the section polygon. Sub-section parcel queries (lots, tracts, easement-level) require commercial-grade survey vendors and aren't part of Township America today.

Step-by-Step: What the Converter Does Under the Hood

If you want to understand how a Texas description is resolved:

Step 1: Parse the Description

The parser identifies which TXSS shape you've given it — Abstract, Block & Section, or Survey — and extracts:

County (by name or FIPS code)
Abstract / block / section / survey-name fields
Optional state ("TX", "Texas", or none)

Step 2: Look Up the Polygon

The parsed fields are matched against the Texas General Land Office's official survey polygons. Each polygon is keyed by (county_fips, abstract_no) or (county_fips, block, section, survey_norm).

Step 3: Return the Geometry

The response includes:

centroid — latitude/longitude of the parcel's center
polygon — full boundary GeoJSON
acreage — computed from the polygon
county_fips + county_name — for downstream joins
survey_name_norm — canonical railroad-survey name (when applicable)

Batch Conversion

Need to convert hundreds of Texas descriptions at once? Use the batch converter:

Prepare a CSV of TXSS descriptions (one per row, in any of the supported formats — they don't need to be uniform)
Upload via the batch interface
Download results with centroid, polygon, acreage, county_fips, and survey_name_norm

Batch jobs accept PLSS and TXSS in the same CSV — you don't need to split them. The parser routes each row to the right engine and returns a system column so downstream code can branch if needed.

Reverse Conversion: GPS to Texas Description

Enter latitude/longitude and Township America returns the underlying TXSS description:

31.4128, -103.8721

returns county, abstract number, and the railroad-survey name of the polygon containing that point — useful for tagging GPS-derived data (drone surveys, well headers, sensor placements) back to legal descriptions.

API Access for Developers

Township America's REST API exposes a unified POST /api/convert endpoint that handles PLSS and TXSS transparently:

# Unified converter — accepts PLSS or TXSS
curl -X POST https://townshipamerica.com/api/convert \
  -H "Content-Type: application/json" \
  -d '{"description": "A-123 Reeves County, TX"}'

See Township America API for the full endpoint reference and authentication.

Tips for Accurate Conversions

Always include the county. Abstract numbers repeat across counties — A-123 in Reeves and A-123 in Bowie are different parcels.
Include the survey name if you know it for Block & Section descriptions — it removes ambiguity when multiple railroad surveys overlap.
Don't worry about abbreviations. T&P, Texas and Pacific, T&P RR Co., and similar all resolve to the same canonical survey.
Use county FIPS if your source data has it — 48389 is more reliable than Reeves Co. in automated pipelines.
Check acreage to sanity-check the match. A Spanish league should be ~4,400 acres; a railroad section ~640. If the acreage is wildly off, you may have hit the wrong abstract.

For teams, batch, and API workflows

If you're converting Texas descriptions at scale — pulling abstracts into ArcGIS, exporting polygons for GIS, or wiring conversions into your own software — see Township America pricing. Plans start at $10/mo. Pro+ ($100/mo) adds polygon export (Shapefile, GeoJSON, KMZ), MCP server, and batch up to 10K rows. Standalone REST API subscriptions are sold separately.

Frequently Asked Questions

What's the simplest Texas description format? Abstract-only — like A-123 Reeves County, TX.

Do I need to know the survey name for Block & Section? Only when the block number is ambiguous across surveys in the same county. If you omit it and the resolver finds a single match, you get the answer; otherwise you get a list of candidates.

Can I batch-convert Texas + PLSS in the same job? Yes. The batch converter accepts mixed PLSS and TXSS descriptions in one CSV.

Does Township America handle Spanish/Mexican land grants? Yes, to the extent they appear in the Texas GLO survey dataset. Pre-Republic-of-Texas historical land grant research beyond what GLO maintains is out of scope.

Can I get Texas polygon exports? Yes — Pro+ subscribers can export Shapefile, GeoJSON, or KMZ for any TXSS description, identical to PLSS exports.
