What's the tech stack? How did you create the website and the data here?
Tiles from esri, map leaflet, and the data is from OpenStreetMap. The power lines were extracted on may 9th using Overpass. We tried to use as many existing (open-source if possible) tools to not reinvent the wheel. Tool layers are a mix of geojsons, and the osmose api. Analytics are umami (open-source). Some statistics in the website come from ohsome.
Country and region layers are from this one geojson I found in a github repo (then condensed and edited by me), and regions are from GADM or openstreetmap boundaries.
