Alan Grant<p>1/ I've posted this kind of thing before: a flight of steps that is not tagged as steps in OSM.</p><p>But this time is different. This time, I didn't find the steps by randomly walking around Malaga. This time, I had A System.</p><p>With the help of the OSMnx package and IGN elevation data, I was able to estimate gradients of street segments in OSM data. The example shows one barrio (Maqueda) that has a flat eastern part, and a western part built on both sides of a ridge. </p><p><a href="https://en.osm.town/tags/OpenStreetMap" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OpenStreetMap</span></a> <a href="https://en.osm.town/tags/osmnx" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>osmnx</span></a> <a href="https://en.osm.town/tags/malaga" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>malaga</span></a></p>
