[OSM-dev] Height information in OSM

[Oleksiy Muzalyev]

Hi Phani,

I am doing an applied research on collecting information for 3D mapping.

For example, here is the link to data page of the Parc Bertrand object: 
https://www.openstreetmap.org/way/4272842

I added the OSM tag:///wikipedia=fr:Parc Bertrand/ to this object, which 
corresponds to this Wikipedia article: 
https://fr.wikipedia.org/wiki/Parc_Bertrand . To the Wikipedia article I 
added the HD aerial image of this park and nearby areas: 
https://upload.wikimedia.org/wikipedia/commons/e/e2/Parc-Bertrand.JPG

The aerial image was taken with a GoPro4Session camera, which weighs 74 
g,  installed on a light quad-copter. It took a couple of minutes to 
take this aerial image. And it covers quite an area. If one zooms this 
HD aerial image, it s possible to count the number of building levels of 
many buildings (and see actual height).

Here are some more Wikipedia articles with my HD aerial images and the 
corresponding tag on the OpenStreeMap map:
https://en.wikipedia.org/wiki/Grandson_Castle
https://fr.wikipedia.org/wiki/Pont_Hans-Wilsdorf
https://fr.wikipedia.org/wiki/Parc_des_Bastions
https://en.wikipedia.org/wiki/Rolle_Castle
https://fr.wikipedia.org/wiki/Parc_Baud-Bovy
etc.

I am working on a new system where HD camera will be carried by a light 
electric glider following a GPS/GLONASS route. In this case I would not 
have to travel to each object by a ground transportation, but I could 
send an ultra-light UAV to take aerial photos and return back. In this 
case more aerial images will be available for 3D mapping.

With best regards,
Oleksiy
