I shot and added as an experiment the aerial sphere 360 panorama to the OpenStreetMap for the lake Lac de Tseuzier: https://www.openstreetmap.org/relation/1642268

The sphere panorama itself is located on the DJI’s website: https://www.skypixel.com/photo360s/spark-78d50747-504a-4a84-90c9-6a02357eb70e .

Here is the link to the same panorama on Google maps: https://goo.gl/maps/GZjbKr1J7hy3WgYU7 , and in the Street-View mode it is shown on the map as a small blue circle.

The area of this lake is about one square kilometer. The size of the panorama file is 1.8 MB. It is created with the Spark quad-copter, which weighs less that 500 grams. Spark creates and publishes the aerial sphere 360 panoramas to the Skypixel website automatically from the DJI Go 4 app.

I added it with the “image” tag. In my opinion, it is time to introduce a new OSM tag for the aerial sphere panoramas.

Last weekend I went to map an archaeological site. I had read a couple of academic archeological papers on this excavation and knew the exact location of the site.

It is a Roman tiles, bricks and ceramic workshop near the town of Chancy which worked for eight hundred years, from 1st century BC till 7th century AD.

This archaeological site was excavated, and then it was covered with earth again for preservation. Still there are antique tiles everywhere around. At that epoch it was a hi-tech enterprise, a place where the Roman Empire was actually built. And it is not completely clear why it was closed after eight centuries of production (an interesting question for today’s reality too).

As a result:

• I mapped the archaeological site on the OSM map: http://www.openstreetmap.org/way/475648607#map=17/46.13281/5.96795

• recorded and published GPS traces of the site to the OSM

• created from scratch an article in the French Wikipedia: Tuilerie romaine des Bois de Chancy . In French because the reference articles are all in French language.

• created Wikimedia commons category: Tuilerie romaine des Bois de Chancy

• created Wikidata item: Q28803317

• added wikidata=* , wikipedia=* , wikimedia_commons=* tags to the OSM object

• made ground and aerial photos for the Wikimedia category (all with GPS coordinates)

• recorded a short video in English on the site and published it to Youtube: https://youtu.be/lS1MyPfVy3o

• converted the MP4 video file to the WEBM format and published the video to the Wikimedia category

I convert video to the open WEBM format, which is accepted by Wikimedia, with the command line tool ffmpeg. Some quality is always lost in conversion, but so far it is the best variant:

ffmpeg -i source.mp4 -c:v libvpx -crf 4 -b:v 18M -c:a libvorbis destination.webm

Geneva is an international city. There are a lot of international organizations in the city: UN, UEFA, WTO, etc.

I am currently working on mapping Geneva with addresses. I use bicycle and [OSMpad] (osm.wiki/OsmPad) for iPhone 4S, and my own free time, mostly on Sundays.

If you want to join this project and do not know how then write me a message and I would provide some tips. To support the project visit my website [www.openbusinessmap.org] (http://www.openbusinessmap.org)

It would take about two years in my estimation to mark all house numbers in Geneva.
