An unmanned aerial vehicle (UAV), is an aircraft without a human pilot on board. Its flight is either controlled autonomously by computers, or under the remote control of a pilot on the ground. The term "drone" encompasses a range of UAV's including the microcopter, mini UAV or small UAV, Micro Air vehicle (MAV), rotor-UAV or RUAV, quadrocopter, hexacopter, octocopter, Bi-copter, Tri-copter, helicopter and Fixed wing planes.

This wiki page is intended at presenting the rationale for the incorporation of UAV* image data in OSM.

We will focus here on a small UAV Framework less than 2 kg,the size is up to 1.5 m and the cheapest price as possible using open source autopilot and software as seen in the table below.

Please note even for recreational use, safety must come first and foremost. UAV's are not toys. Use extreme caution when operating a UAV. Avoid flying over crowds or over people as far as is possible. Follow a UAV ground course. Consider getting UAV insurance. Check for and follow local laws at all times.

Camera

Time-lapse (intervalometer) fixed-lens cameras which can take pictures continuously are available in the market[1], but as First Person View with a permanent link is preferred to see where you fly if the UAV goes out of sight the HD WiFi cameras and cell phones with wireless and GSM are getting more common at the moment. For multi purpose cameras, The US Agricultural Research Service en Science Applications International Corp reduced the costs of near-infrared spectroscopy by using a standard 12-Mpixel camera that didn't use a hot-mirror filter to block the NIR spectrum and added an additional optical Wratten number filter.[2] Considder the gimbal suspension and side protection frames to protect your camera on landings.

Range Extenders

To extend the range standard HDMI Long Range Wireless Extenders[3] (Wireless (Wifi) Repeaters) are used up to 984 feet (400-450 m) line-of-sight. Cellular GPRS modems can be used.[4] A cheap solution is to combine a CC3D and EzUHF 4-Channel RX with PPM.[5] A tracking station comes in different sizes.[6] An omni type antenna for short range and your directional antenna like a helical, yagi or patch.

Data import to OSM

OpenStreetPhoto used its OpenStreetPhoto/QuadCopter for UAV image data in collaboration with Opengeo [7]. In a later stage it moved to a Fixed Wing configuration. The Vertical_Aerial_Photographs#Homebrew section has some links on how to import.

Image recognition software

Consider using image recognition software to spot roads in the software.(and call your local emergency number if you spot a fire) [8][9]

FAQ

What's the benefit of using aerial imagery rather than satellite imagery?

When updating cartography over disaster or slum area, the resolution of images is an issue. A one-hour UAV flight can provide a coverage of 2 km² with a pixel resolution of 4 cm and a DEM (Digital Elevation Model) at 10 cm resolution. In contrast, satellite imagery can cover a large area (20*20 Km) for one tile with a resolution of 50 cm.

So both satellite imagery and UAV/aerial photos are essential to have a better accuracy in a specific area — they are complementary.

With an UAV, the only weather-related constraint is the wind and the rain, but it is still possible to take pictures e.g. under clouds.
