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

Hi,
There seems to be lot of 3D mapping going on by using OSM data. Can
anyone help me in understanding how to model a city in 3D using OSM
data where height tag is not so common. Is there anyone working on 3D
mapping? if so how could you get the height information for the features?
Thanks
Phani
