Design posters showcasing your country's electrical grid
Turns power lines into wall art, but the comments stole the spotlight
TLDR: Grid2Poster turns public map data about power lines into stylish posters of countries and even continents. People loved the look, but the comments quickly swerved into jokes, geography corrections, and rival map links—making the real spectacle the community reaction.
A new project called Grid2Poster lets people turn their country’s electricity network into sleek, print-ready posters using public map data. In plain English: it takes the giant web of power lines that keeps the lights on and turns it into something you could frame in your living room. That alone was enough to get the community swooning, with one commenter instantly asking where people even print something that fancy, clearly already imagining a California grid poster above the couch.
But this being the internet, admiration lasted about five seconds before the nitpicking, joking, and nerdy one-upmanship rolled in. The funniest reaction came from someone who said they were “really hoping” for full-on propaganda posters for or against national power grids, which honestly sounds like a much messier and more entertaining spin-off. Another commenter brought instant correction energy, pointing out that one showcase image was Africa and, well, “Africa is not a country.” Ouch. Tiny geography note, giant comment-thread energy.
Then came the classic internet flex: people linking rival tools and better data sources. One person dropped OpenInfraMap like a casual mic drop, while another suggested a North America alternative that’s supposedly more complete in the US because it doesn’t rely on community-edited mapping. So the vibe was equal parts “this is gorgeous”, “your labeling is off”, and “nice project, but here are three other maps.” In other words: a perfect comment section.
Key Points
- •Grid2Poster generates print-ready electrical grid posters from OpenStreetMap data using GeoPandas, OSMnx, and Matplotlib.
- •The tool supports countries, states, provinces, and continents, with optional administrative boundaries and optional inclusion of minor lines and cables.
- •Data quality depends on OpenStreetMap coverage, and the article recommends MapYourGrid for improving mapped transmission infrastructure.
- •Users can export outputs as PNG, SVG, or PDF, and can also export all fetched transmission lines as a GeoJSON FeatureCollection in WGS84 (EPSG:4326).
- •Continent rendering uses Natural Earth admin-0 boundaries because Nominatim does not resolve continent names, and large runs may require hundreds of Overpass API queries and several hours.
