Historically, Texans have turned to the Texas General Land Office for maps and other tools used to organize information about the natural resources this state has to offer.Besides historical maps, research, and data, the land office today 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. The Land Office website contains a collection of dynamic interactive mapping websites 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 Texas General Land Office. The Land & Lease Mapping 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 imagery.
Texas Beach Watch
The goal of the Texas Beach Watch program is to provide the public with information about water quality at selected recreational beaches along the Texas coast.
Find Your Perfect Beach. From fishing and boat ramps, to camping and BBQ—the Texas Coast provides a wealth of resources to all visitors. The GLO is proud to offer this free resource to help you explore all that our shores have to offer.

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. These codes include recommendations from the following external resources: 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) is sediment related geospatial and geotechnical data. TxSed can be used to assist in identifying 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.

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 a safer and higher opportunity area.

Texas Beach Adopters Map
The Texas General Land Office has been sending this message across the state for twenty-eight years, and Texans have responded. Since the first cleanup in 1986, more than 481,000 Texas Adopt-A-Beach volunteers have picked up more than 9,100 tons of trash from Texas beaches, some of it originating from as far away as South America. Each of the Texas Beach Adoptor groups mapped here has committed to cleaning up its adopted beach three times a year for two years. Many adopters are long time stewards of Texas beaches and renew their membership year after year.
GIS Map Data
Beach Access Points
Public beach access points mapped by the GLO in cooperation with coastal towns and counties.
Coastal Leases (Point Locations)
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 (Polygonal Locations)
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 Environmental Sensitivity Index classification (sensitivity of shoreline habitats to oil contamination and removal). Classification conducted by the University of Texas Bureau of Economic Geology.
This layer 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.
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 January 2017 Lease Sale Nominated Tracts
Tracts that have been nominated for the quarterly Oil & Gas lease sale

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.
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
This layer contains parcels that have been identified as properties that are owned by different state agencies that have been reviewed to have a mineral interest whether all or in part. An in-depth research of the records would have to be performed to make an actual determination of mineral status. (The collection is not complete and is a work in progress for adding addition parcels.)
State Submerged Lands
State-owned tracts in offshore waters and coastal bays. These tracts are owned and leased by the GLO.
State Tracts with Resource Management Codes
State-owned tracts in offshore waters and coastal bays, with codes added that reflect restrictions and concerns associated with leasing of these tracts.
Three Marine League Line
The boundary between state and federal jurisdiction located three marine leagues (approx. 10 miles) offshore in the Gulf of Mexico.
Three Nautical Mile Line
Line of demarcation three nautical miles offshore of the Texas coast in the Gulf of Mexico.
