      <a class="moz-txt-link-freetext" href="http://wiki.openstreetmap.org/wiki/Aviation">http://wiki.openstreetmap.org/wiki/Aviation</a> is fair enough,
      especially the main principle: "We map anything that is observable
      on the ground.", but not an airspace. A communication tower, or a
      mast is well observable on the ground.<br>
      <br>
      The DJI changed the map on its RPAS control stations from Google
      to Here Map. And on Here Map not much is shown. So usually one
      looks at several maps while planning a flight, especially in an
      urban area.<br>

          <span>Dear Martin,</span><br>
          <span></span><br>
          <span>An air traffic obstacle, a tall structure which can
            endanger air traffic, has to be marked with red and white
            colored markings and with aircraft warning lights at night.
            If you look at these communication towers this is how they
            are actually painted.</span><br>
          <span></span><br>
          <span>An airman say a pilot of a medicopter may well study
            terrain carefully on a map before a flight. In fact it is
            not a flight as a bird flies, but rather a jump as there is
            a time limit, an endurance. That is why a planning is
            necessary.</span><br>
          <span></span><br>
          <span>Unfortunately on the OSM map he/she will not see any
            icon. At the same time the air-traffic in urban areas will
            continue to increase. It is future of urban mobility [1].</span><br>
          <span></span><br>
          <span>If a helicopter, an RPAS, a plane touches a mast or a
            cable it would crash; a mast may collapse. For individuals
            involved it could certainly be a disaster.</span><br>
          <span></span><br>
          <span>People do realize it. Andy not only mapped the
            communication tower (or mast) but plans to map its cables.
            It is a good idea too. It will take time to map all these
            towers (masts), measure and calculate their height, etc.</span><br>
          <span></span><br>
          <span>Unfortunately the confusion between "man_made=tower" and
            "man_made=mast" continues. One is rendered and one is not,
            and that adds to confusion.</span><br>
