Dear Martin,


You are right. For photos it is clear. Some photo-cameras are even 
capable to add coordinates to photos, and then /Camera location/ lat and 
lon fields at the Wikipedia upload page are filled in automatically.


However, it is not so clear for videos. Wikimedia allows now to upload 
HD videos. For example, last weekend I filmed a documentary video of 
/Fort des Rousses/ and added it to the Wikipedia page [1]. It is the 
second by territory military fort of France, 21 ha, constructed in the 
19th century. I filmed it from the ground walking around its walls and 
from the air flying around.


The nearby lake /Lac des Rousses/ [2] is even larger, 0.9 km2. My aerial 
and ground cameras moved around it while filming quite long distances.


In such cases I select the middle of the area which was filmed at the 
OSM map Share section, copy & paste the link to a text editor, remove 
parts of the URL leaving only two real numbers of lat and lon, and then 
I add these coordinates manually to the Camera location lat and lon 
fields at the Wikimedia upload page. It requires some additional manual 
work, a text editor, but it is doable and even kind of simple. But I 
could not explain this process to a non-IT colleague via e-mails even 
with screen shots.

With best regards,
Oleksiy

if viewing videos)
