MapTiler<p>Use our beautiful hand-drawn <a href="https://bsky.brid.gy/hashtag/hillshade" rel="nofollow noopener" target="_blank">#hillshade</a> on medium-scale maps! We’ve updated the hand-drawn hillshade layer so you can use it on <a href="https://bsky.brid.gy/hashtag/maps" rel="nofollow noopener" target="_blank">#maps</a> that show small countries or states. Use it together with the terrain-RGB layer to highlight the relief of the map.
