GeoDC : June 2026 Meetup
**The next GeoDC will be held on Wednesday, June 10 from 6-9pm at Sudhouse DC (1340 U St NW, Washington, DC 20009) with the program starting at 7pm.**
* Join us early from 6-7pm to grow your network, socialize and grab drinks and appetizers.
* Throughout the evening, we'll be sharing job announcements and details of other GIS/Geo upcoming events we're tracking.
* We look forward to seeing you on the 10th!
**Our Program will feature these presentations:**
**The Secret History of the Blue Dot - William H. Tewelow, GISP (GPS World)**
This presentation takes the audience from an iconic movie scene they recognize but never understood, through the hidden origins of GPS, and returns them to the blue dot in their own hand, seeing it for the very first time. There is a blue dot on your phone right now. It knows where you are to within a few feet. You have never questioned it. You have never wondered where it came from.
You should.
Its origins are classified. Its lineage runs through the Cold War, nuclear submarines, and a doctrine built on the promise of mutual annihilation. The technology that tells you where to turn was designed for something else entirely.
The technology did not change. Only the purpose did.
**GEOINT Symposium's Golden Ticket Program - Katie Weintraub (ESRI)**
This is a firsthand account of USGIF's GEOINT Symposium Golden Ticket — a program built for early-career professionals who want to level up their careers.
Participants get free admission to GEOINT Symposium, mentorship opportunities, a network of fellow Golden Ticket alumni, and a cohort of peers to grow alongside.
This talk breaks it all down fast — what it is and why it's a stellar experience for young professionals breaking into or already working in the geospatial intelligence realm.
**From GIS to AI: Lessons from MIT’s Applied Data Science & AI Program**- **Julia Brodsky (Navy Federal Credit Union).**
A practical look at one GIS professional’s experience completing MIT’s Applied Data Science & AI Certificate program, including key takeaways, challenges, and thoughts on how AI may impact the geospatial industry.

Mid-Week Service
## **Mid-Week Service: Renew Your Spirit**
Join us every **Wednesday evening at 6:15 PM** for our Mid-Week Service, a dedicated time to pause, pray, and recharge in the middle of a busy week. Held in an intimate and welcoming setting, this service is designed to help you reconnect with God and find peace through His Word.
### **What to Expect**
* **Deep Biblical Teaching:** We move beyond the surface, engaging in verse-by-verse studies of Scripture—such as our current journey through the **Book of Acts**—to gain practical wisdom for daily life.
* **Community Prayer:** We believe in the power of collective intercession. Each week, we lift up the needs of our families, our city, and the world.
* **Heartfelt Worship:** A time of singing and reflection to center our hearts on the presence of the Holy Spirit.
* **Authentic Fellowship:** Connect with a supportive community of believers who are walking the same path of faith.
Whether you are looking for a deeper understanding of theology or simply a quiet place to sit at the feet of Jesus, our mid-week gathering offers the spiritual nourishment you need to finish your week with strength and purpose.

⚡️ Side Projects and Networking: DSDC Meetup
RVSP on Luma!: https://luma.com/thq3hut1
Join us for an evening of data science side projects and networking! Come hear lightning talks about what people are building, meet other people working on cool stuff, and hang out.
Whether you're deep into a side project, just getting started on one, or curious about what other people are working on, this is a good place to be. Side projects are how a lot of us learn new tools, explore ideas, and connect with people—and they're a lot more fun when you have other people to talk to about them.
The speakers tonight are folks who have been participating in our side project mentorship program since March. They submitted side projects they wanted to work on, got matched with mentors, and spent 12 weeks working on them. They'll be talking to you about some aspect of what they did or learned.
**Schedule**
* 6:00 - 6:30PM: Mingling & food & drinks
* Lightning Talks!
* **Bryan Johns** — "Floodlines: The Geography of Institutional Memory"
**Karen Zhu** — "Historic Recipe Explorer: Bringing Historic Cookbooks to Life with AI"
**Aaron Schumacher** — "Pave the Planet: A new data visualization technique"
*
We'll add more as they come in.
Speakers! TBA, but I'll add them as they come in!

We Built an AI Platform Using AI — Here's What We Learned
A small team of AWS Solutions Architects not traditional software engineers, built AIRE Traffic Control (ATC), a production agentic AI platform now serving thousands of builders. We used AI at every stage: spec-driven development, AI-generated code, automated testing, and agentic workflows. In this talk, we'll share the real story, the architecture, the failures, the breakthroughs, and what we learned about driving adoption from 32% to 92% in 10 weeks.
You'll walk away with practical patterns for building multi-agent systems, using AI-DLC methodology, and empowering non-traditional dev teams to ship production-grade applications.

Stop Guessing: A Product Person's Guide to AI Adoption
## 🤝 Host Information
A co-hosted event by ProductTank Columbus & Women in Product Columbus
💡 About the Workshop
AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge.
This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow.
Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required.
🛠️ What to Bring
Laptop: Fully charged and ready to go.
AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!)
🍕 Logistics & Perks
Food & Drink: Pizza and drinks provided!
Parking: Plenty of free spaces available on-site.

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
