2015 Statewide Orthoimagery Project

More background about the project

Project Activity for the week ending
May 6th, 2016

Update Summary

  • The entire statewide orthoimagery dataset at 0.5-meter pixel resolution is now available for download from TNRIS! DOQQs in Mexico are not downloadable (yet) but available per request from TNRIS.
  • TNRIS launched web mapping services (WMS) for the 2015 TOP and Buy-Up datasets. Access the urls below under TOP 2015 Online Mapping Services and avoid downloading the data. Currently, only West TX and the Panhandle are available in the statewide service.
  • TNRIS continues to ship final 0.5-meter DOQQs to Esri for integration into their Basemap Imagery Service, publicly available through Esri products NOW: West TX, Panhandle, and North TX 0.5-meter. Avoid downloading the data. See access instructions below under TOP 2015 Online Mapping Services. Buy-Up 6-inch/1-foot orthoimagery will also be available.

Data Acquisition and Processing Progress

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.

  • 100%

    of the state has been flown for 0.5-meter imagery (see the note above)

  • 100%

    of the state has been surveyed for ground control

  • 100%

    of the state has been begun initial image processing

  • 100%

    of the state has been processed through aerotriangulation

  • 100%

    of pilot data received

A Statewide Resource

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.

Contributors

Four state agencies contributed funds toward the BASE 0.5-meter statewide orthoimagery collection.

Acquisition Season

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).

Pixel Resolution

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.

1-Foot Buy-Up Option

6-inch Buy-Up Option

Spectral 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.

High Priority Imagery and Data Sets Contract

The High Priority Imagery and Data Sets (HPIDS) Contract was used to select the orthoimagery provider, Surdex Corp., from a pool of prequalified geospatial data providers.

The contract is held by the Council on Competitive Government and administered by TWDB/TNRIS.
