An unmanned aerial vehicle (UAV) may navigate to place a ground structure, having a known location, into a field of view of a camera and capture imagery of the ground structure. Algorithms may be used to identify the ground structure to determine its known location. Ground structures may include identifiers that provide the known location and/or other information to enable determination of the known locations. Algorithms may determine an offset distance of the UAV from the ground structure to enable determination of a location of the UAV. For example, the images may be used to determine a distance and angle(s) from the ground structure when the ground structure is shown in a perspective view and has features that indicate orientation. In some embodiments, the UAV may transmit its location to other UAVs, and/or may create and/or transmit a corrected GPS location based on the location determined by the ground structure.
