Patent attributes
An electronic device that determines a height of a transceiver in a structure is described. During operation, the electronic device acquires an image of the structure. Then, the electronic device receives user-input information that specifies lines on the surface of the structure, and receives second user-input information that specifies an approximate vertical location on an exterior of the structure of a transceiver in the structure. Moreover, the electronic device obtains a second image from above the structure from an imaging service, and receives third user-input information that specifies at least one of the lines on the surface in the second image. Next, the electronic device provides information to the imaging service, and in response receives a distance between end points of at least one of the lines. Furthermore, the electronic device provides second information to a computer, and in response receives the determined height of the transceiver.
