About Open Data Day

To promote civic engagement and smart city innovation in North Texas, this event is all about collaboration between cities and citizens to turn problems into opportunities, and ideas into products that can have a measureable, positive impact on their own community.
Open Data Day is a 100% community organized event by TechMill, a registered 501(c)(3) nonprofit focused on building community through networking, events, and education!

The Future of Smart Cities

Above: See how smart cities are rising to meet the challenges of rapid urban development.

Cities are constantly improving their technology infrastructure to keep pace with the modern world. Data has become the single most important decision making tool that helps our local governments make better choices on urban planning and infrastructure development based on evidence to benefit our communities.

Open Data Day is a day long event aimed at supporting cities and communities across North Texas who are investing and researching in new ways to improve the lives of everyday citizens through technology. This event is a chance for those passionate about civic technology, government transparency, and open data to utilize their skillsets in building applications, tools, and prototypes that support smart city initiatives.

How can my city participate?

The purpose of Open Data Day is to integrate passionate technologists with innovative cities to validate or prototype new smart city projects, or brainstorm and address problems city officials see in their own community that could be positively addressed through technology. Are you a city with a project? Visit our sponsor page for more information, or directly.

Here are some categories of projects that could be pitched at Open Data Day.


What can we do to better monitor our air quality or gather better data for more robust air quality data?


How do we encourage citizens to ride bikes, walk and use transit more instead of riding in cars alone?


How can we increase the number of residents utilizing our renewable energy programs or incentives?

Public Safety

How can we provide an easier, more accurate way for citizens to submit safety issues for the cities to review?

Who can attend?

For those who think Python isn't a pet and JSON isn't the name of a deli, then you're already halfway there! Open data events are technical in nature and needs developers who can take solution concepts and turn them into practical applications. Whether you're piecing together APIs or building on top of a new framework or mobile app- developers are crucial to delivering projects.

A user interface is like a joke - if you have to explain it, it's not very good. Designers can provide invaluable insight into the user interface and user experience when developing a new product. Developers and designers go hand-in-hand to delivering functional and usable software.

A project without a purpose is just code and colors. Non-technical participants can encompass a number of roles, but generally doumentation, video editing, infographics, or subject matter experts who can provide insight, logic, and reason as to what the projects are actually trying to solve.

The first part to getting involved is showing up! This event is not limited to "professionals" by any means. Whether you're an expert in NodeJS or blockchain - or just trying to apply those C++ courses into a practical project - this event will provide you with invaluable experience.

What's in it for me?

The Thrill

What is Open Data Day?

Open Data Day is a gathering of citizens to write applications, liberate data, create visualizations and publish analyses using open public data to show support for and encourage the adoption of municipal open data policies. It is a great opportunity for college students and local developers to use open data from cities around North Texas to produce something useful to their own communities.

All you need is yourself, your tech setup (laptop, charger, headphones, etc), and a great attitude - we'll provide the rest!
