Covering posts from 0800 ET November 7 to 0800 ET November 8. Sources: 168 geospatial feeds.
Quiet day across the feeds. Only seven posts landed in the window, and a weekend lull like this doesn't support a full three-topic briefing. Here are the highlights.
1. Thermal Drone Data Acquisitions: CalVal project with Informatics — Earth Observation News A small cooperative project at the Earth Observation Research Cluster is building an active thermal calibration panel so drone temperature readings can be trusted when conditions change fast. It's the kind of sensor-physics and calibration work the landscape notes as thin in EO coverage, and it comes from students and researchers instead of a vendor. → Thermal Drone Data Acquisitions: CalVal project with Informatics
2. City Population Estimates 2020-2025 — Decision-Making Information Resources & Solutions Of the U.S. population of 341,784,857 in 2025, an estimated 63.1 percent lives in one of 19,484 incorporated cities. About 75 percent of those cities have fewer than 5,000 people. It's a useful demographic baseline for anyone building location analytics. → City Population Estimates 2020-2025
3. Contrasting Political Maps of Population Density in Eastern Asia — GeoCurrents It argues that comparing China with its neighbors can mislead because most Chinese province-level divisions are similar in scale to whole neighboring countries. A good reminder that choropleth results depend on how the units are drawn. → Contrasting Political Maps of Population Density in Eastern Asia
4. Utopian London — Maps Mania For the #30DayMapChallenge, the author fed an aerial image of Trafalgar Square into Gemini to produce a pixelated, greener and more cycle-friendly version. It's a small, concrete example of generative AI used as a map-making step. → Utopian London
5. Fast Pitches Winners 2026 — GoGeomatics It recaps the Fast Pitches session at the GoGeomatics Expo in Calgary, where 11 presenters got three minutes each on the main stage. It's thin on analysis, but it shows who Canadian geospatial startups are putting forward. → Fast Pitches Winners 2026
