**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.

THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER **PLEASE REGISTER WITH CAPITAL PHOTOGRAPHY CENTER, NOT MEETUP!** https://capitalphotographycenter.com/classes/class/2026-05-09-exploring-street-photography Street photography is very popular now more than ever because photographers have access to high quality cameras in mobile phones and smaller high resolution digital cameras. A camera’s ease of access and proliferation raises the issues of ethics and privacy in public places and the difference between a snapshot and a street photograph. This hands-on class will explore the unique aspects of the street photography genre. Michael Koren will be your guide as you create compelling photographs that go beyond the ordinary snapshot. First, you’ll learn pro level tips and techniques and discuss privacy issues associated with street photography. Then, with Michael’s guidance and direction, the group will head out to photograph near the White House in Lafayette Square. You’ll create photographs that demonstrate your personal vision while using your own gear optimized for street photography. We'll then head back to the classroom for image reviews and feedback. Topics include: -Proper techniques and settings for street photography -Pro tips and techniques for capturing compelling images -Create captivating images using anticipation, patience, composition and visualization -Hands-on image capture -Privacy and ethics concerning street photography -Image review and feedback Recommended gear: -Although any camera will do, for best results we recommend a DSLR or mirrorless camera with manual exposure controls -Lenses in the range of 28mm - 70mm (zoom or prime) -Fully charged camera battery with an optional spare -Camera instruction manual (paper or electronic) -No tripod, no flash Class size is very limited *** • Important to know **THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER** https://capitalphotographycenter.com/classes/class/2026-05-09-exploring-street-photography

From the parking lot, the Group heads to the Great Falls Tavern Visitor Center and crosses the bridge over the C&O Canal in a northerly direction toward the Washington Aqueduct Observation Deck overlook. The Group heads south down the trail to the Great Falls Overlook on Olmsted Island Overlook to photograph the Potomac River waterfalls, kayakers, great blue herons, and other birds. That trail takes the Group across a couple of waterfalls, where great shots are taken. The estimated full walk is two miles (3.2 kilometers).

This is also not a business networking event. It’s a calm space to connect with nature and, if it feels natural, with like-minded people. 🌿 What to expect: • A slow-paced, relaxed walk • Moments of silence and observation • Simple reflection prompts 📍 Location: [ Red Trabue Nature Preserve] ⏱ Duration: \~60 minutes This is a small, initial gathering as I begin creating this space through WellGratiVibes — a blend of mindfulness, nature, and quiet connection.

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!
