Texas Imagery Service

A Geographic Resource for Texas Government Agencies, Easy to Access, Utilize and Incorporate into the Work you do for the Public.

Easy to Use Imagery for Government Entities Across Texas

Many of us use Google imagery in our daily lives, whether looking up directions or exploring our neighborhood from above. The State of Texas has collaborated with Google to provide a cost-efficient and widely accessible mapping tool that meets the needs of government agencies - the Texas Imagery Service.

The Texas Imagery Service is designed to provide high resolution imagery showing the entire state of Texas with its most current coverage. The service provides continuous 6-inch natural color imagery for the entire state.

Making Google imagery available to all public agencies in Texas distributes the cost, making the imagery and the updates affordable to all.

The transition to the Google Cloud Platform (GCP) is now complete. Unique links are being distributed to current pilot participants and will be completed by August 31st. The new service provides faster response times, the ability to export and print maps, and contains the newest imagery for several areas in Texas.

Google has also cached all imagery down to level 20 (True 6-inch resolution). This provides an extra level of detail in the imagery service.

Please Note: By default, ArcMap version 10.2.2 or prior will only display to level 19. There is a patch that will allow prior versions to consume level 20. The effect on CAD and Microstation users is unknown at this time

General FAQ

GENERAL FAQ

How can the Texas Imagery Service help my organization?

The Texas Imagery Service serves 6-inch, natural color imagery for the State of Texas.

It provides state organizations with a current and consistent data source while offering the highest resolution imagery available for any statewide program through an OGC compliant Web Map Service (WMS) and Web Map Tile Service (WMTS).

Google hosts the Texas Imagery Service through its latest Google Cloud Platform technology. It provides significant cost savings by streaming imagery directly to your GIS or application. There is no need to pay large storage costs for serving terabytes of data.

How is the Texas Imagery Service different from the imagery seen in Google Earth and Google Maps?

The Texas Imagery Service has a higher level of positional accuracy (~0.5m) because it has been reprocessed using existing ground control points where available (mostly in high density urban areas). Imagery can be downloaded for on-premise use and archiving under a perpetual license agreement. The Texas Imagery Service can be used in all state and local government web applications without an API key, including those applications that are not public facing or require a login. The Texas Imagery Service can be used to derive data and the imagery can be incorporated into base map services, etc., without restriction.

Who can use the Texas Imagery Service?

The Texas Imagery Service is a restricted license and is only for use by public organizations in the State of Texas (ie. state, regional and local governments). Contractors for any public organization are permitted to use the imagery as long as the project or program being performed directly supports the public organization.

Rights to use the imagery terminate upon completion of work by the outside entities. The sponsoring agency will need to request an imagery link on behalf of any contractor or outside 3rd party.

How will maintenance and imagery update costs be covered in the future?

During the pilot year, which extends through March 2016, the GIS Solutions Group will review options for a fair and reasonable cost-recovery model using usage metrics and other factors. The more that play the less we all pay.

UPDATE - The Texas Imagery Service will be available without a fee through August 21, 2017.

I don’t use the Google Maps API, how can I incorporate the services into my tools and applications?

Google Maps API provides access to the rich mapping content services from Google. Maps API is a commercial product that requires licensing based on quantities of use but is not required to access the Texas Imagery Service.

The Texas Imagery Service is an open-standard service and can be incorporated into a wide variety of GIS software and web mapping applications that support open-standard formats such as the Esri suite of products, QGIS, or Global Mapper.

Check with your IT Department or software provider to determine if an OGC compliant Web Service is supported by your applications.

How is the Texas Imagery Service different from the State Programs currently in place to acquire imagery such as the Texas Orthoimagery Program (TOP) or the National Agriculture Imagery Program (NAIP)?

The Texas Imagery Service is a mapping service that is available on-demand. It is licensed, hosted, and served by Google. It offers 6-inch resolution imagery, which is four times higher resolution than the 1/2-meter Texas Orthoimagery Program (TOP) imagery and approximately 16 times greater resolution than the 1-meter National Agriculture Imagery Program (NAIP) imagery.

The imagery represented by the Texas Imagery Service is not in the public domain and is restricted under license.

Will the state continue to pursue its own acquisition of statewide imagery such as the Texas Orthoimagery Program (TOP) and National Agriculture Imagery Program (NAIP) partnerships?

Yes, TNRIS will continue to work in coordination with partners to determine the need for orthoimagery. Persisting situations will call for new statewide leaf-off (TOP) or leaf-on (NAIP) acquisition projects to meet higher specific requirements (resolution, positioning) or even greater currency than Google’s update cycle goals (targeted for a 3 year refresh cycle around the State). Additionally, at the federal level, we currently expect the statewide 1 meter 2-year NAIP updates, contracted by the USDA, and the high resolution NGA 133 Cities imagery programs to continue. These products are different enough from the Google imagery, in terms of acquisition schedule and specs, that they should be complementary data resources.

If you feel that an unauthorized party has compromised your links, please contact TNRIS immediately. We will disable your current links and re-establish new links for you to use.

How much does the service cost for my agency?

The Texas Google Imagery Service is a per annual subscription service paid in full for each year of participation. The participation year runs from September 1 to August 31 each year.

Cost for the service is distributed across state, regional, and local government based on the amount of data usage. There are "tiers" within each level of government:

State Agency

Level Data Usage* Costs**
Tier 1 Power $375,000
Tier 2 Advanced $125,000
Tier 3 High $62,500
Tier 4 Moderate $31,250
Tier 5 Minimum $15,625

Regional Agency

Level Data Usage* Costs**
Tier 1 High $30,000
Tier 2 Moderate $20,000
Tier 3 Minimum $10,000

Local Agency

Level Data Usage* Costs**
Tier 1 High $24,000
Tier 2 Moderate $12,000
Tier 3 Minimum $6,000

* Data usage is calculated based on service requests over a 90-day period multiplied by 4 for an annual metric.

** Cost does not include DIR Fee

Data usage is calculated each year and adjusted for the next year's renewal.

Can I join at any time during the year?

Yes. Your initial annual cost will begin at the lowest tier for your government agency (state, regional, or local) and prorated through August 31.

The Texas Imagery Service now contains layers by year. What are these new layers?

A view of the layers in ArcMap
A view of the layers in ArcMap
There are several layers in the WMTS and WMS Texas Imagery Service. The “Texas” layer contains the most current imagery available for Texas. As new imagery become available for 'block' areas in Texas (Ex. Dallas, Houston, etc), the older imagery are placed into the yearly layers depending on the year the imagery was flown. For example, the Austin block in the ‘texas-2016’ layer shows imagery flown in 2016 because this block was updated with imagery flown in 2017 represented in the ‘Texas’ layer.

Layer Descriptions:

Texas

Statewide mosaic of latest available imagery in the Texas Imagery Service. This layer includes years 2017, 2016, 2015, 2014, and a small portion from 2013. To determine date of imagery, please refer to the instructions received with your unique link or request access.

This layer contains imagery captured by Google in 2017 that is now archived to the texas-2017 layer after new imagery became available. This layer will eventually contain all imagery collected in 2017.

texas-2016

This layer contains imagery captured by Google in 2016 that is now archived to the texas-2016 layer after new imagery became available. This layer will eventually contain all imagery collected in 2016.

texas-2015

This layer contains imagery captured by Google in 2015 that is now archived to the texas-2015 layer after new imagery became available. This layer will eventually contain all imagery collected in 2015.

texas-2014

This layer contains imagery captured by Google in 2014 that is now archived to the texas-2014 layer after new imagery became available. This layer will eventually contain all imagery collected in 2014.

texas-2013

This layer contains imagery captured by Google in 2013 that is now archived to the texas-2013 layer after new imagery became available. This layer will eventually contain all imagery collected in 2013.

texas-2012

This layer contains imagery captured by Google in 2012 that is now archived to the texas-2012 layer after new imagery became available. This layer will eventually contain all imagery collected in 2012.

texas-2011

This layer contains imagery captured by Google in 2011 that is now archived to the texas-2011 layer after new imagery became available. This layer will eventually contain all imagery collected in 2011.

texas-basemap

This layer includes roads, county boundaries, major water features, and city names available as base information while using the service.

Hurricane Harvey image layers

These layers include imagery flown over some of the affected areas during the Hurricane Harvey event. They include Corpus Christi flown on 8/30/2017, Houston flown on 8/31/2017, and Lake Charles/Beaumont flown on 9/2/2017 & 9/3/2017.

If your GIS/CAD software can ingest a WMTS, discontinue using the WMS link and begin using the WMTS link throughout your organization. WMTS is optimized for efficient web delivery and map printing.

If your GIS/CAD software cannot ingest a WMTS, continue to use the WMS link.

Both of your unique WMS and WMTS links will continue to serve the Texas Google imagery to your organization.

Known issue: The WMTS may present offset imagery in ArcGIS version 10.1. The offset is not an issue in 10.3.

Esri is aware of this issue and has temporarily resolved it until it can be fixed in the next release. Add the following text to the end of your unique WMTS link - /wmts?service=wmts&VERSION=1.0.0&request=GetCapabilities

Ex. https://txgi.tnris.org/login/path/xxxx-xxxxxx-xxx-xxxx/wmts?service=wmts&VERSION=1.0.0&request=GetCapabilities

The WMS link is compatible in ArcGIS Online.

Why does my downloaded tile imagery look blocky/patchy when displayed in ArcGIS?

If you are adding the downloaded imagery tiles (not the Service) into ArcGIS, open the Layers Properties dialog and make sure to uncheck the “Apply Gamma Stretch:” option and to set the “Stretch” type to None.

Note: Because the Texas Imagery Service is a restricted license, it is only for use by public organizations in the State of Texas.

Contractors or any individual working on behalf of a public organization are permitted to use the imagery as long as the work being performed directly supports the public organization. The sponsoring agency will need to request an imagery link on behalf of any contractor or outside 3rd party.

How do I know if and when new imagery has come online?

To learn about new imagery or any updates to the Texas Imagery Service, please visit the status section at the top of this page.

View Status Updates

We will continually monitor and update this section to provide the information and history of all updates relating to the service.

No. Your current links should be updated automatically and always reflect the latest imagery. However, during the pilot year, there may be some platform adjustments that will occur that would warrant the creation of new links. For example, Google is phasing out the Google Maps Engine platform in favor of their Google Cloud Platform (GCP). This change is expected to occur late in 2015 for Texas. Once this happens, new links will need to be created for all users. TNRIS will do our best to notify all users well before the change takes place so that you can plan accordingly.

What if I see errors or inconsistencies in the imagery? How should I report it and to whom do I report it?
