Hi John,<br>
<br>
It is possible to add a <i>wikipedia, wikimedia-commons, wikidata </i>[1]
to provide a reference to an article in Wikipedia, Wikimedia, or
Wikidata about the feature on the OSM map. Wikimedia accepts now HD
video files up to 5 GB, as it built a new data center. <br>
<br>
So what we can do is to film a short documentary about a feature
using both aerial and ground footage, upload it to a respective
Wikimedia page, then add reference of a video a Wikidata and
Wikipedia page, and finally add <i>wikidata</i> and legacy <i>wikipedia
& wikimedia-commons </i>to the OSM map. I provide some
examples of such my videos [2]. If there is no time to film and edit
a video it could be just oblique low-altitude aerial & ground
images [3]. <br>
<br>
It could be not only a video about a building, but about an area,
say a lake [4].<br>
<br>
It became much easier to film such videos as there are nowadays
readily available aerial and ground cameras with an active gimbal
stabilization. Besides weather forecasts also became more accurate,
so it is possible now to plan a filming expeditions in advance.<br>
<br>
Having a aerial & ground footage of an object one can add <i>building:levels</i>,
<i>height</i>, <i>leaf_type</i>, <i>amenity=parking</i>, and other
information for the whole adjacent area.<br>
<br>
We can expect that in future the resolution of aerial cameras will
became even higher. The same about an UAV range and reliability. <br>
