US: A startup called Airmap has raised $2.6 million in seed funding to expand its airspace-mapping and data visualisation system. Basically, Airmap has created software to help drone operators fly only where they are allowed and welcome to do so. The California-based company is a member of the NASA Unmanned Traffic Management programme. And it is working collaboratively with industry partners to display off-limits areas on maps. The company maintains a registry of no-fly zones to log the preferences of private citizens, businesses and other organisations on the ground. This is particularly important because places like schools and hospitals may not want drones to pass overhead, even if it is legally allowed to do so in that area. Lux Capital led the seed funding round.
