Covering posts from 0800 ET May 30 to 0800 ET May 31. Sources: 161 geospatial feeds.
Quiet day across the feeds — a typical weekend overnight, with only three substantive posts in the window. The richer Sunday material (the PostGIS 25th-anniversary tributes, the Cloud-Native Geospatial Forum's "usefulness over openness" framework) landed just after this window closed and will carry into tomorrow's briefing. Here are the highlights.
1. GeoLibre v0.5.0 significantly expands geospatial data format support — Open Geospatial Solutions A release walkthrough for GeoLibre, covering broadened format support in an open-source geospatial library. Open Geospatial Solutions is one of the few voices producing applied, video-format tooling content — squarely in the persistently underserved practical-tooling gap. Worth a look if you want to see the format support in motion rather than read a changelog. → Watch on YouTube
2. The legacy of Dijkstra — Spatialists Ralph Straumann flags a new Veritasium video tracing Dijkstra's shortest-path algorithm from early GIS to modern wayfinding, and the techniques — Nested Dissection, Contraction Hierarchies — that get routing answers back in microseconds. A clean reminder that the routing most of us treat as a solved black box rests on decades of layered algorithmic work. Good curation from a consistently sharp source. → Read on Spatialists
3. 1918 Geographic Center of the Lower 48 States — Lebanon, Kansas — EarthStuff A historical-cartographic curiosity: in 1918 the U.S. Coast and Geodetic Survey, lacking the compute to integrate an irregular landmass, found the geographic center of the contiguous 48 by cutting the map out of cardboard and balancing it on a pin — accurate to within ±20 miles. A nice antidote to the day's algorithmic theme: the same problem, solved with a pin instead of a solver. → Read on EarthStuff
