A system for high temporal and high spatial resolution monitoring of a field of plants is disclosed. Illustratively, the system includes a plurality of ground based reference objects, a balloon adapted to be positioned above the field of plants, and a balloon positioning system coupled to the balloon and configured to position the balloon relative to the field of plants. An imaging system is supported by the balloon and includes a locations system, at least one camera, and at least one gimbal configured to orient the at least one camera. The imaging system captures at least one image of the field of plants including the plurality of ground based reference objects in the at least one image. |

1. An aerial positioning system comprising:
a balloon; a balloon positioning system coupled to the balloon and configured to position the balloon at a desired balloon elevation, a desired balloon latitude, and a desired balloon longitude, the balloon positioning system including a plurality of winches supported on the ground, and a plurality of tethers extending between the winches and the balloon; a sensor system supported by the balloon, the sensor system including
a location system which determines a balloon elevation, a balloon latitude, and a balloon longitude,at least one sensor directed to a ground based region of interest, andat least one gimbal configured to orient the at least one sensor; and a controller in communication with the balloon positioning system and the sensor system, wherein the at least one sensor provides to the controller a first set of data at a first time related to the region of interest, and a second set of data at a second time related to the region of interest, and the balloon positioning system positions the balloon at the desired balloon elevation, the desired balloon latitude, and the desired balloon longitude in response to input from the location system at both the first time and the second time. |
