  • Understanding Map Zoom Levels and XYZ Tile Coordinates
    When working with interactive maps, two concepts sit at the foundation: zoom levels and tiles. Without them, platforms like Google Maps, Leaflet, or MapLibre GL would be impossible. Instead of loading one massive image, modern maps are composed of tiles โ€” small 256ร—256 px squares that fit together in a grid. As you zoom in, the number of tiles grows exponentially, providing more detail at higher levels. - Source: dev.to / 10 months ago
