The 6-inch orthoimagery covering the San Antonio River, southeastern Wilson County, Karnes County, and Goliad County, TX were flown during the 2015 leaf-off season in late March.Category: Orthoimagery - Regional
The 6-inch orthoimagery covering portions of the following TX counties: Andrews County, Crane County, Crockett County, Loving County, Pecos County, Reagan County, Terrell County, Upton County, Ward County, Winkler County were flown during the 2015 leaf-off season in early March.Category: Orthoimagery - Regional
The 6-inch\12-inch orthoimagery were acquired in 2015 during leaf-on conditions. The dataset covers three small areas: Hidden Pines near the City of Bastrop, Hueco Tanks near the City of El Paso, and Powderhorn Ranch near the City of Port O'Connor.Category: Orthoimagery - Regional
The 12-inch orthoimagery were acquired in 2015 during leaf-on conditions. The dataset covers four citywide areas: Amarillo, Dallas-Fort Worth, El Paso, and Lubbock.Category: Orthoimagery - Regional
We're excited to announce that all acquisition flights have been completed!
Note: Due to unfavorable weather conditions, it wasn't possible to acquire the remaining areas of Texas (9%) within the original timeframe. Flights were put on hold on in early August 2015 until the next upcoming leaf-off season, pushing the estimated project completion date to Spring 2016.

The 2014-2015 Statewide Texas Orthoimagery Project fulfills the charge led by TNRIS to develop statewide aerial imagery as a base map resource for state, regional, and local government entities.
The program regularly acquires consistent and updated aerial imagery in order to develop geospatial products throughout Texas. These data are used to identify current conditions, features, and changes on the ground serving as a base of reference for other map information.
In 2013 we started gathering interest in new statewide orthoimagery flown during the leaf-off time period. In early 2014 we secured sufficient funds to release an RFO for statewide acquistion and selected Surdex Corporation as the data provider, officially beginning data acquisition in October 2014.
Follow regular updates as we continue updating this page with weekly status reports and other news.

Four state agencies contributed funds toward the BASE 0.5-meter statewide orthoimagery collection.
Five additional government agencies contributed funds toward select 1-foot or 6-inch BUY-UP areas.
All orthoimagery products are acquired during the leaf-off (fall/winter) season in TX.
Leaf-off imagery allows manmade structures under deciduous tree cover to be mapped or monitored more easily than using leaf-on imagery. Vegetation mapping can also be beneficial with leaf-off imagery because evergreen vs. deciduous species are more readily identified.
Grab the Image Slider to compare between Leaf-Off imagery (left; Feb 16, 2010) and Leaf-On imagery (right, Nov. 9, 2011).
The BASE statewide orthoimagery will be acquired and processed at 0.5-meter pixel resolution.
Select BUY-UP areas will be acquired and processed at either 1-foot or 6-inch pixel resolution. The following are example features identifiable in each resolution.
All orthoimagery products will be available as 4-band images.
These may may be displayed as natural color (Red, Green, Blue) or color infrared (Near Infrared, Red, Green) composites, as seen in the examples below.
