Historically, Texans have turned to the Texas General Land Office for maps and other tools used to display and organize information about the state’s rich natural resources.

Besides historical maps, research, and data, the Land Office uses Geographic Information Systems (GIS), global positioning systems (GPS), and computer-aided design (CAD) systems to compile, analyze, and distribute the most accurate information possible about the location of natural and human-made resources. These tools support the business functions of the General Land Office and serve as critical tools in the study and protection of our state's valued resources. This page contains a collection of dynamic, interactive mapping viewers, as well as downloadable GIS layers, that give Texans access to the vast collection of spatial data available at the agency.

GIS Map Viewers

Land & Lease Mapping Viewer

The Land & Lease Mapping Viewer, an interactive mapping application, provides access to vast collections of land and energy-related data at the General Land Office. The Land & Lease Viewer displays upland and submerged Original Texas Land Survey boundaries, Permanent School Fund land, upland and coastal leases, oil and gas well locations, and current aerial imagery.

Resource Management Codes  

Resource Management Codes (RMCs) are assigned to state-owned tracts in Texas bays and the Gulf of Mexico, providing development guidelines for activities within each tract. The codes enhance protection of sensitive natural resources by providing recommendations for minimizing adverse impacts from mineral exploration and development activities. The codes include recommendations from the U.S. Fish and Wildlife Service, National Marine Fisheries Service, Texas Parks and Wildlife Department, Texas Historical Commission, and the U.S. Army Corps of Engineers.

Texas Coastal Sediments Geodatabase

The Texas Coastal Sediments Geodatabase (TxSed) contains sediment-related geospatial and geotechnical data. TxSed can help to identify compatible sediment resources for proposed beach nourishment or habitat restoration projects, and can be used as an aid in the permitting/regulatory processes for such projects.

State of Texas Oil Spill Response Mapping Tool

The State of Texas Oil Spill Response Mapping Tool (STORM) contains information from the Oil Spill Toolkit, EPA National Disaster Operational Workgroup, TABS Buoy Gulf of Mexico weather, and new tools like the advanced drawing tool.

Homeowner Opportunity Program Area Locator Mapping Application

The Homeowner Opportunity Program (HOP) is a disaster recovery housing program through which income-qualified applicants, who live in FEMA-designated “High Risk” areas or areas of high minority and/or poverty concentration, may elect to rehabilitate or reconstruct their existing home, or relocate to safer and higher opportunity areas.

Texas Beach Adopters Map

Adopt a stretch of beach today! Are you committed to helping ensure Texas beaches are trash-free? Then consider adopting one! Our adopters pledge to clean a designated stretch of Texas coastline, a minimum of three times a year for two years. Many adopters are long-time stewards of Texas beaches, and renew their membership year after year. With this interactive map, learn which stretches of Texas beach are available for adoption.

GIS Data


The Aerial Collection covers flights from 1938 to the present of various areas within the Coastal Zone.

Beach Access Points

Public beach access points mapped by the GLO in cooperation with coastal cities and counties.

Coastal Leases (Points)

Locations of structures and activities permitted by the GLO within state-owned land and waters. Includes features represented by a single point location, such as piers, docks, breakwaters, and shoreline protection projects.

Coastal Leases (Polygons)

Locations of structures and activities permitted by the GLO within state-owned land and waters. Includes areal features such as dredging areas, parks, mitigation projects, and conservation easements.

Coastal Zone Boundary

The official boundary of the Texas Coastal Management Program (CMP). The area lying generally seaward of the coastal facility designation line, which is the line adopted under the Oil Spill Prevention and Response Act of 1991, to describe areas where oil spills are likely to enter tidal waters. The layer also includes wetlands landward of the coastal facility designation line, generally within one mile from the shoreline, along the extreme inland reach of certain tidal rivers and streams.

Dispersant Use Pre-Approval Zone

Boundaries of pre-approved area for use of dispersant in oil spill response. Boundaries were created by combining the 10-meter offshore bathymetric contour and the three nautical mile line. The boundary follows whichever line is farthest offshore. Data are not to be used for navigation or for mapping at large scales.

Environmental Sensitivity Index Shoreline

Shoreline of Texas with sensitivity classification of habitats to oil contamination and removal. Classification conducted by the University of Texas Bureau of Economic Geology.

Hard Minerals

Contains basic information about active Hard Mineral Leases (minerals other than oil & gas) issued by or through the General Land Office. The information in this layer represents a snapshot in time. As new leases are added, expired, or terminated, they are removed from the active layer.

In-Situ Burn Exclusion Areas

Areas, designated by the Oil Spill Regional Response Team VI, where in-situ burns are prohibited.

Navigation Districts

Submerged lands granted with mineral reservations by the Texas legislature to Navigation Districts.

Oil & Gas Leases

Oil and Gas Leases managed by the Texas General Land Office.

Oil & Gas Units

Oil and Gas pooling agreements managed by the Texas General Land Office.

Oil & Gas August 2017 Lease Sale Nominated Tracts

Pipelines and Miscellaneous Easements

Pipelines located in state-owned submerged lands and other areas along the Texas Gulf Coast.

Priority Protection Habitat Areas

Priority coastal habitat areas to be protected during oil or hazardous material spills on the Texas coast. Areas were identified and prioritized by TPWD and GLO personnel, in cooperation with other entities.

Species & Habitats

Coastal distribution of animals, plants, and habitats potentially at risk from oil spill damage or response activities. Mapped as part of a joint project involving GLO, TPWD, and other entities.

State Agency Lands

Contains tracts identified as owned by various state agencies, that have a mineral interest, whether all or in part. In-depth records research is necessary to make an actual determination of mineral status. (The collection is not complete and is a work-in-progress, with regular addition of new parcels.)

State Submerged Lands

State-owned tracts in bays and gulf waters, owned and leased by the GLO.

State Tracts with Resource Management Codes

State-owned tracts in bays and gulf waters, owned and leased by the GLO, with codes added that reflect restrictions and concerns associated with leasing of these tracts.

Three Marine League Line

Boundary between state and federal jurisdiction, located three marine leagues (approximately 10 miles) offshore in the Gulf of Mexico.

Three Nautical Mile Line

Line of demarcation three nautical miles offshore in the Gulf of Mexico.

Upland Leases
