**The next GeoDC will be held on Wednesday, May 6 from 6-9pm at Sudhouse DC (1340 U St NW, Washington, DC 20009) with the program starting at 7pm.** We’ve got 3 presentations scheduled for the evening– Please check out the program details below. Join us early from 6-7pm to grow your network, socialize and grab drinks and appetizers, compliments of our sponsor for the month, [Voyager](https://www.voyagersearch.com/). Please remember to [RSVP through the GeoDC Meetup page](https://www.meetup.com/geo-dc/), and we hope to see you in a few weeks. *If you’d like to present or sponsor a future GeoDC Meetup, please complete this [form](https://forms.gle/QbAXPfrDnX12GGaS8).* **Brian Davidson:** **Zero to Map: A 10-Minute Geospatial Speedrun with Gemini** * Think building a functional mapping application requires hours of boilerplate and API frustration? Think again. In this talk, we’ll race against the clock to build a live mapping app from scratch using Gemini and Antigravity. You’ll see how to leverage LLMs to handle everything from a mapping provider integration to complex coordinate rendering in minutes. Whether you’re a seasoned GIS pro or a curious dev, my hope is you'll leave with a better understanding of how to turn your idea into a working map before your coffee gets cold. **Noah Goodman**: **Voyager** * The Voyager platform has enabled customers to resolve data management issues, such as duplication, lack of governance & metadata. Demos of the Voyager platform capabilities and will discussion of a recent State DOT project. **Dr. Aditya Kapoor: Assessment of Inundation Dynamics in Nebraska Using AlphaEarth Foundations** **Embeddings** * This study demonstrates that AlphaEarth Foundation Embeddings (AFE) provide a highly efficient, "analysis-ready" framework for mapping regional surface water inundation without the computational burden of traditional multi-source data fusion. By applying Random Forest classifiers to AFE data across 901 Nebraska lakes from 2017 to 2025, I found that this method outperformed existing products like Dynamic World, which exhibited estimation errors of up to 43.8%. The analysis revealed a critical environmental trend: a mean inundation decline of over 6,600 m² per year, closely mirroring a regional rainfall reduction of 14.18 mm/year. Ultimately, the findings highlight AFE as a scalable tool for identifying hydrological instabilities, particularly in smaller water bodies, offering significant advantages for real-world water resource planning and flood risk assessment.

Join Service Design DC for a community movie night focused on learning, reflection, and connection through two keynote presentations from last year’s Service Design Global Conference. SDGC25 brought the global service design community together around the theme “Business Transformation by Design,” exploring how service design can influence strategy, operations, and customer experience across organizations. For this gathering, we’ll watch 2 selected talks from SDGC25, then open up a casual group discussion about what resonated, what feels relevant for our work now, and what these ideas might mean for service design practice in DC. The 2025 conference centered on service design’s role in helping organizations navigate cross-functional transformation, making these talks especially relevant for practitioners working across systems, teams, and change. **What to expect** * Watch 2 selected presentations from SDGC25 together. * Casual facilitated discussion after each talk. * Time to connect with other service design and adjacent practitioners in the DC area. **Evening Agenda** 6:00 P.M. - Doors Open + Socializing & Networking 6:30 P.M. - First talk highlights + conversation 7:15 P.M. - Second talk highlights + conversation 8:00 P.M. - Wrap up **Many thanks to our host and sponsor, MediaBarn!** *Mediabarn’s customer-centric philosophy defines who we are.* *In its simplest form, we are committed to applying Human-Centered Design (HCD) methods to understand customer needs, collect feedback, and use that feedback to improve services and products. Whether it’s for customers, citizens, or employees, our Experience Design Studio creates research-informed designs to improve the experience of every human involved.*

James is out of town this week, so let's draft my variant of the famed 100 Ornithopters cube, featured in [this video by Rhystic Studies](https://www.youtube.com/watch?v=Pddm1gbBuWE). My list is slightly different, but keeps the same design philosophies, although there might not be exactly 100 Ornithopters. The cube has no creature tokens, no creature lands, and no ways to kill your opponent without the card having something to do with controlling or having Ornithopters. My cube list is below: [https://cubecobra.com/cube/list/100ishornithopters](https://cubecobra.com/cube/list/100ishornithopters) The event will take place at a **NEW LOCATION** in Arlington, near Ballston Quarter, and the Ballston metro, accessible through the Orange and Silver lines! Feel free to contact me through Meetup or call me at 9194578870 if you have any questions about getting to the location. **CONDUCT POLICY** We cultivate a safe, friendly atmosphere. Please keep other's feelings close to mind. Derogatory comments of any kind are unacceptable, as is behavior that may make others uncomfortable, such as rage-quitting. If the stresses of the game are getting to you, we encourage you to politely sit out for a while. Thank you!

**Tired of surface-level conversations?** Join us for *Ditch the Small Talk*—an evening of deep, real connection with strangers who are down to go there. We’ll meet in the grass in front of the cathedral, break into small groups, and draw questions from a deck of cards designed to spark vulnerable, honest conversations. How it works: Draw a card and ask a question. Listen. Don't coach or give advice without permission. Try to ask follow-up questions when people share. You can spend 1 minute on a question or 1 hour, just go with the flow. **If you show up late, please don't interrupt the speaker. Just sit down in a group of your choice and they'll bring you up to speed when whoever is talking finishes. Bring a blanket or chair if you don't want to sit in the grass. *** Rules*** 1. Don't debate politics 2. Keep what is shared in the group within the group 3. If you need to use your phone, step away from your group first

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
