1. An unmanned aerial vehicle (UAV), comprising:
a body;
a camera in a fixed position with respect to the body;
at least one propeller coupled to the body;
a global positioning system (GPS) coupled to the body;
a 3-axis magnetometer coupled to the body;
memory containing a flight path having camera capture points; and
a control system configured to control the UAV along the flight path, the control system having a processor configured to determine a first heading of the body using the GPS and a second heading using the 3-axis magnetometer and determine if the headings are correlated or uncorrelated, wherein the control system is configured to determine if the flight path is unprogrammed, wherein the control system is configured to unilaterally decide to return the UAV to a home station when the headings are not correlated and the flight path is an unprogrammed path;
wherein the processor is configured to automatically determine the flight path based upon a GPS position of the camera capture points and a predetermined pitch angle of the camera at the camera capture points.
