Covering posts from 0800 ET March 6 to 0800 ET March 7. Sources: 113 geospatial feeds.
Quiet day across the feeds — here are the highlights.
1. GPS Jamming and the Iran War — The Map Room Jonathan Crowe flags that GPS jamming in the Persian Gulf is hitting commercial shipping as collateral damage from the Iran conflict — the same pattern playing out across every active conflict zone. Short and well-framed; treats jamming as structural rather than exceptional, which is the correct read. Unusually practical PNT commentary from a non-defense perspective. → Read it
2. Spirent Bridges the Gap Between Field and Lab PNT Testing with Industry-First Solution — Earth Imaging Journal Spirent (now part of Keysight Technologies) launched SimXTRACT, a GNSS test tool aimed at replicating real-world signal conditions — including jamming and spoofing environments — inside a lab. Landing the same day as the Map Room's GPS jamming piece, this is a useful juxtaposition: the threat context and the tooling response arriving together. → Read it
3. IOU Compliance Strategies for Complex PUC Reporting — Fulcrum A rare commercial vertical post: investor-owned utilities managing PUC regulatory reporting across wildfire mitigation, vegetation management, and infrastructure inspections. Fulcrum's argument is that compliance succeeds or fails at the point of field data capture — not at filing time. Commercial GIS in utility operations is structurally underrepresented in the feeds; a concrete applied piece worth reading if that vertical is relevant to you. → Read it
4. ArcGIS Maps SDKs for Game Engines at the 2026 Esri Developer & Technology Summit — ArcGIS Blog One of two ArcGIS Blog previews (game engine SDKs and web development) dropping ahead of the Esri Developer & Technology Summit. Conference promo, but the game engine SDK track is worth watching — it's one of the more genuinely novel directions in how geospatial data gets rendered and interacted with outside traditional GIS contexts. → Read it
5. Archive Movie Maps — Maps Mania Keir Clarke's daily curation surfaced a roundup of archive movie maps — historical film geography visualizations. Lighter fare, but representative of the web mapping creativity that Maps Mania reliably surfaces and that the rest of the ecosystem largely ignores. → Read it
