**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.

What does it look like when ideas come to life? Join NOVA Scribes and MAFN for a full-day, in-person open house where the public is invited to step inside the world of facilitation. This is a come-and-go experience designed for curiosity, exploration, and conversation. Whether you are new to facilitation groups, you are welcome. The space will be set up as a "theater in the round," (see the image) with facilitators working live around the room. Throughout the day, you will see different techniques, styles, and modalities demonstrated in real time, from visual templates, facilitation tools, and decision-support methods. You can observe, ask questions, and engage directly with the practitioners as the work unfolds. **What you can expect** * Live demonstrations of facilitation techniques * Multiple practitioners working simultaneously, each with their own approach and style * Short, informal demos and tiny teaches that explain how and why specific techniques are used * Opportunities to talk one-on-one with experienced facilitators * A chance to see how facilitation can support sensemaking, alignment, and group dialogue **What you might explore** * Methods and templates for planning, strategy, and reflection * Facilitation methods that support participation and decision making * Tools, materials, and setup considerations for live work This open house is designed to be accessible, hands-on, and inspiring. You do not need to stay all day. Come for 20 minutes or stay for hours. Watch ideas take shape. Notice how facilitation can change the energy in the room. Ask the questions you have always wanted to ask. If you have ever been curious about how facilitation works and supports groups, this is your chance to experience it up close. **Open to the general public. No prior experience required.** We’re not charging for this workshop, but we will be asking for donations!

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!

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.
