Regional North American conference for free and open-source geospatial software. No edition was held in 2020-2022 (the organizer's past-conference list goes from San Diego 2019 to Baltimore 2023; no online edition found). The 2023 schedule and sponsor wall were Whova embeds that are no longer available, so 2023 speakers and sponsors are partial; 2024-2026 programmes come from pretalx at talks.osgeo.org. Recordings are published by Project Geospatial. No 2027 edition announced as of November 2026.
