**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.

How about a Happy Hour over unbeatable prices. Instead of silently doing research on your own, it is well known that when you are regularly connected with people of your own investment interest, you are likely to be more motivated, better informed and less likely to miss out on opportunities. Meet and discuss face-to-face. METRO : Please take into account Metro's Weekend Track Work & Service Adjustments. Check it on http://www.wmata.com/ and plan accordingly.

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.*

Discover DC Boundary Stones in Maryland - NW Stone 4 (Delcarlia Reservoir Grounds) to North corner stone (Silver Spring). This is the third hike along the original boundary line between the nation's capital, Virginia, and Maryland. See stones placed every mile along the boundary survey line in 1792. These stones are the first federal monuments in the nation's capital. Initially, we will hike a short distance along the Capital Crescent Trail to view NW Stone 4, which is on Delcarlia Reservoir grounds. We will come back to our meeting location and hike north along Norton Street and Loughboro Road (restroom opportunity at Sibley Hospital) to Delcarlia Parkway. We will hike a short distance along Delcarlia Parkway and then on Spring Valley neighborhood streets to Warren Place and Delcarlia Parkway, where we will get you as close as we can to the location of NW Stone 5, which is also on Delcarlia Reservoir grounds. We will hike Spring Valley neighborhood streets to Massachusetts Avenue and Western Avenue at Westmorland Circle, and then on sidewalks along Western Avenue (NW stones 6, 7, and 8 are in front yards along Western Avenue), on trails through the northern portion of Rock Creek Park (NW 9 is adjacent to the park), and on sidewalks along streets in Silver Spring (North corner stone is just south of East-West Highway, west of 16th Street) to the Silver Spring Metro Station. Total distance is approximately 10.5 miles. We will meet 9:00 am, Friday, May 9, 2026, at the connector trail to the Capital Crescent Trail (intersection of Norton Street and Potomac Avenue NW). Parking is available along Potomac Ave. Public transportation to and from the hike also works. If you drive, you can take Metro and a bus back to your vehicle. Occasional restroom opportunities are available along the route. All participants must sign a liability waiver at the start. SCPRO requests a voluntary donation of $2 per person to help support our all-volunteer program. Leaders are Russ Norfleet & Gary Kosciusko.

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!
