confused about #postgis ST_NPoints with polygons, because a triangle apparently has 4 points.
SELECT ST_NPoints(ST_GeomFromText('POLYGON ((0 0, 0 1, 1 0, 0 0 ))'));

🤔 Wondering if your idea for a FOSS4G NA talk is “good enough”?
Great talks share lessons learned, useful workflows, or practical demos others can use. Submit your presentation proposal before the deadline.
At FOSS4G NA, the most memorable sessions are those that inform, include, and encourage others to engage with the growing open geospatial ecosystem. A strong presentation connects open geospatial tools and data to real-world outcomes, moving beyond simply describing technology. The most effective ta
