Hello! I'm new here, thanks for running this great forum. I'm not very competent about drones, only used a few toys in the past. In order to check the state of an almond field, which is located at 4 km from my home, I need a drone that can fly autonomously from my home to the site at a given altitude, when arriving lower the altitude, take shots at different places, return at high altitude, and fly back home. I'm in Europe so that would be within CE rules, so hopefully the drone should be able to complete the mission even if the remote is out of range for some time. Please could advice me about a possible solution? Note: I'm willing to spend more for a solution which is capable of automatically avoid collisions by using advanced sensors. Thanks.
