Beyond GIS Layers: A Spatiotemporal Knowledge Graph of Bainbridge Island

CUGOS (Cascadia Urban GIS Open Source) · Wednesday 21 October 2026, 6:00–7:30 pm · Bloedel Hall, Room 292, University of Washington, Seattle · Event page

How my Let’s Map Bainbridge project goes beyond map layers to connect people, places, buildings and vessels across time on Bainbridge Island. The talk covers CityGraph, the knowledge-graph platform I built for it, and how the graph joins OpenStreetMap, local-government GIS and museum records.

Slides will be posted here after the talk.

Keeping unfinished features in the main branch behind switches, separating deploy from release, flags by user and group, canary and percentage rollouts, A/B testing, and testing both states of every switch. It drew on running feature flags in production at RECON Dynamics, first with my own open-source Django Feature Flipper and then with Waffle.
