<div>Hi Blake,<br>
<br>
A quadrocopter cannot be flown higher than 150 meters due to
regulations. Usually a flight in a city happens happens like this.
I carefully select a takeoff & landing ground. It could be a
lawn in a park, a grass area, empty construction site, etc.
preferably early in the morning. <br>
<br>
I switch on the GoPro to make one photo per second, then I take
off and fly only above this empty area. So practically it is out
of the question to fly above a city freely to make orthorectified
imagery of the whole city. However panoramic low altitude (50 -
150 meters) aerial photos could be shot in all directions and are
complimentary to satellite imagery. And it is possible to find
such an area for takeoff and safe landing almost everywhere.<br>
<br>
As for programming this feature, an image is just uploaded,
coordinates and camera direction are saved in a database for this
image. Maybe also a rating system.<br>
<br>
Prosumer UAVs progressed a lot this year. Now it has a Fail Safe -
returning to the point where it took-off automatically, Home-Lock,
- if a pilot lost orientation, it starts moving to the pilot the
shortest way, Course-Lock - independent of yaw, forward remains
forward (very useful at altitude higher than 100 meters, when it
is hard to see the UAV's orientation). So it is relatively easy
and safe to pilot. It also has now self-tightening propellers. I
takes about a minute to put them on for a flight and remove for a
compact transportation.<br>
<br>
Also this year the GoPro 4 Session camera appeared. It weighs only
72 grams. F450 DJI can easily carry two such cameras. Opposite to
the StreetView approach it is not necessary to walk or drive every
street to film it.
<span lang="en"><span>A dozen or two of</span> <span>flights</span>
<span>in good weather will cover</span> <span>the entire city.<br>
<br>
And as I already said the system is very robust. Even if a
crash happens, having built it from an ARF kit oneself makes
it just a mater of several minutes to exchange a spare part or
two. If there is a special layer for 50 - 150 meters aerial
photos on the OSM map, it is quite realistic that people could
start shooting such aerial photos and upload. I hope to learn
more on this subject at the conference next month.<br>
<br>
Best regards,<br>
Oleksiy<br>

Hi,
<br>
<br>
OpenAerialMap is designed to take georeferenced aerial imagery and
make it publicly available for mapping.
<br>
<br>
OpenDroneMap is processing only software, but you do end up with a
stitched together georeferenced, orthorectified image and point
cloud files.

Btw, what is current state of special services to share the

openstreetphoto is dead, mapilliary could almost be used [1],
but it is
<br>
not really optimised for it. With drone imagery software you get
3D
<br>
models “for free” as part of processing/SfM, you often (but not
always)
<br>
georeference your data etc. Anyone knows about on
opendronephoto

project yet?
<br>
<br>
Sharing with plain photo sharing service just does not feel
right.

Good morning,
<br>
<br>
Here are some of panoramic aerial images which I made in
Odessa,
<br>
Ukraine, with the quadrocopter F450 DJI (flight controller
Naza V2
<br>
with GPS) and camera GoPro 4 Session. One such an image may
cover
<br>
several square kilometers. It does not substitute satellite
imagery,
<br>
but provides useful information for mapping: building
levels,
<br>
land-use, etc.
<br>
<br>
And it is not necessary to have hundreds of photos for just
one
<br>
street as with a Street-View approach. So it is not
necessary to
<br>
have the newest servers for such a layer.
<br>
<br>
City of Odessa, Ukraine:
<br>
<a href="https://goo.gl/photos/Jnt4TaXuxyw7j6kR8" target="_blank">https://goo.gl/photos/Jnt4TaXuxyw7j6kR8</a>
<br>
<br>
and town of Bilhorod-Dnistrovs'kyi:

<br>
<br>
to get the HD photo download it, do not save from the
browser screen.
<br>
<br>
<a href="https://goo.gl/photos/Jnt4TaXuxyw7j6kR8" target="_blank"><https://goo.gl/photos/Jnt4TaXuxyw7j6kR8></a>F450 DJI is
assembled from
<br>
the ARF (almost ready to fly kit), so it is easy to upgrade
and
<br>
repair. It is a robust flying platform. Let alone camera
GoPro 4
<br>
Session.
<br>
<br>
Mapillary accept aerial images but a flight should be only 4
- 5
<br>
meters above the ground. I published several aerial images
on Google
<br>
Maps though, and the number of views is in thousands. Images
are to
<br>
be geo-tagged before publishing to Google Maps.
<br>
<br>
There will be the conference "How drones changing your
business" in
<br>
Lausanne, Switzerland, on September 14th and 15th 2015:
<br>
<a href="http://droneapps.co/" target="_blank"><http://droneapps.co/></a><a href="http://droneapps.co/" target="_blank">http://droneapps.co/</a> . Among
attendees are
<br>
DJI, Airbus, Lufthansa, SenseFly, DB Bahn, SNCF, and others.
<br>
<br>
I am also experimenting with fixed-wing UAVs. It is much
harder to
<br>
learn to pilot well, but a fixed-wing UAV is capable by now
to fly
<br>
about 200 km along a waypoint route with an autopilot.
<br>
<br>
So the idea is to implement such a panoramic aerial imagery
layer at
<br>
the OSM.
<br>
<br>

<br>
Oleksiy
