Mapbox gl js contour lines + elevation
<p>How can we add contour layers with elevation labels to our map? I found this: <a href="https://www.mapbox.com/blog/satellite-map-with-contours/" rel="nofollow">https://www.mapbox.com/blog/satellite-map-with-contours/</a> , but it doesn't show how. I also found this: <a href="https://www.mapbox.com/mapbox-gl-js/example/toggle-layers/" rel="nofollow">https://www.mapbox.com/mapbox-gl-js/example/toggle-layers/</a> , but the contour lines have no altitude information.</p>
