[OSM-dev] Playback of Camera Movement in OSM2World Question

Hi Peter,

I am intrigued. I plan to install OSM2World and follow it.

I work on the problematics from another side. I work on using real flights to capture data for 3D mapping and make it readily available for all mappers.

It is possible to publish 3D aerial images both into a Wikipedia article and a respective Wikipedia category. There's an OSM tag also for a category.

Here are the aerial images of Collège Madame de Staël in Geneva which I made with the DJI Phatom 3 this week:



An advantage of Wikipedia is that it keeps the original images resolution, so building:levels are well visible. Google Maps automatically reduces resolution.

DJI Phantom 3 has got the range of 2.2 km, and the new Phantom 4 has got the range of 4.5 km (3 miles). But the range is also limited by the constant visual contact required by law. So actually it is about 1 km (and the maximum allowed altitude 150 meters in this case). Still it is enough to cover quite a large area.

Phantom 4 has got increased reliability due to doubled systems, but in any case it's recommended to perform hundreds of training flights before even considering a takeoff in a city.

DJI Phantom writes coordinates and altitude into JPGs Exif automatically, so an automation is possible.

Best regards
