===Summary===
In order to facilitate safe and coordinated delivery by UAVs (unmanned aerial vehicles), this patent provides a landing platform. This platform is placed on a safe place, away from individuals, preferably above the roofline. The platform can sense dangerous situations, and communicate with the UAV to guide it, or abort the delivery if a safe landing is not possible. Besides that, the platform may also be connected to the inside of the building, so it can transport packages between floors.

This patent describes a platform that is placed on the roof of a building, which can receive drone deliveries. By means of an elevator, the package is then transported to a lower level, so a person can actually receive the parcel. Also, it suggests several ways of identificating the right platform/drone, such as RFID, a QR-code, and so on.
