1. A method of generating a composite image of a subject from a first image and a second image, the method comprising: receiving, by a service component operating on a computing device, a request for the composite image of the subject; selecting, by the service component in response to the receiving the request, a first device from a plurality of devices, the selecting the first device based on stored device information that indicates that the first device is configured to provide at least a first portion of the requested composite image, the first portion corresponding to the first image of the subject, wherein data storage includes the stored device information for each of the plurality of devices including for the first device and the second device, and wherein each stored device information comprises a DeviceID that identifies a corresponding device, and a geographic location of the corresponding device, and other characteristics of the corresponding device, and wherein the geographic location of each device in each corresponding stored device information is updated by a device tracker; selecting, by the service component in response to the receiving the request, a second device from the plurality of devices, the selecting the second device based on the stored device information that indicates that the second device is configured to provide at least a second portion of the requested composite image, the second portion corresponding to the second image of the subject; transmitting, in response to the selecting the first device, a first request to the first device for the first image of the subject; transmitting, in response to the selecting the second device, a second request to the second device for the second image of the subject; receiving, in response to the first request, the first image of the subject from the first device and, in response to the second request, the second image of the subject from the second device; and synthesizing, in response to the receiving the first image of the subject and the second image of the subject, the requested composite image of the subject based on the first image of the subject and second image of the subject.
