Attribution

Required by license. Where, what, how.

What you must show

© OpenStreetMap contributors · © MapsForDevs

Both attributions, every map view, on every device.

When the map shows raster satellite (phase 2):

© OpenStreetMap contributors · © MapsForDevs · © Maxar Technologies

Where it lives

• Style.json (recommended): attribution property on each source. MapLibre auto-renders it in a small expandable control bottom-right.
• NOT in PMTiles header: our pmtiles archives contain zero attribution metadata. This keeps the data clean and lets you control attribution per surface.

MapLibre default control

new maplibregl.Map({
  style: {
    sources: {
      mfd: {
        type: 'vector',
        tiles: [`https://tiles.mapsfordevs.com/tiles/{z}/{x}/{y}.pbf?key=${KEY}`],
        attribution: '© <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> · © <a href="https://mapsfordevs.com">MapsForDevs</a>'
      }
    }
  }
});

Hide the default control only if you render attribution elsewhere:

new maplibregl.Map({ ..., attributionControl: false });

Custom attribution UI

You may render attribution in your own component as long as it remains visible while the map is shown.

<div class="custom-attr">
  © <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a>
  · © <a href="https://mapsfordevs.com">MapsForDevs</a>
</div>

.custom-attr {
  position: absolute; bottom: 4px; right: 8px;
  background: rgba(255,255,255,0.85);
  font-size: 11px; padding: 2px 6px; border-radius: 3px;
}

Both attributions and the © symbol must be present. Links are required and must be clickable.

Print / export

When exporting a static image (PNG, PDF, screenshot for marketing), attribution must be burned into the image. The export helpers we ship handle this automatically.

Mobile

iOS / Android MapLibre Native render the attribution control by default — leave it on. For iOS you may move it; do not hide it.

Embed widget

The free embed widget always renders both attributions. You cannot remove them from embed.mapsfordevs.com URLs.
