DroneDeploy, a drone software startup, on Thursday said it raised $50 million in a funding round that comes as an increasing number of large companies use drones for surveying purposes.

Its software instructs drones on where to fly, what to capture visually and then analyzes that data for companies, Mike Winn, co-founder and chief executive of DroneDeploy, told Reuters.

The latest round was led by existing investors Energize Ventures and AirTree, and brings the total funding to date to $142 million. Winn said the investment will be used to develop its software so it can also be used with ground robots and to accelerate expansion into Europe.

DroneDeploy offers a Cloud platform to simplify commercial drone operation. They are enabling farmers, contractors and researcher to create aerial maps, and 3D models of their operation with just 2 taps on a smartphone.
