Methods and systems for analyzing a field

1. A method of analyzing a field, the method comprising:

positioning an imaging system in an aircraft;

acquiring with the imaging system an aerial thermal image of at least a portion of the field while the aircraft is in flight over the field;

georeferencing the aerial thermal image by superimposing the aerial thermal image on a geographical map of the field to obtain a georeferenced aerial thermal image;

providing the georeferenced aerial thermal image to a user interface;

indicating with the user interface a location on the georeferenced aerial thermal image to be inspected in the field;

operating an unmanned aerial vehicle to fly over the location in the field, the unmanned aerial vehicle having a camera, means for location tracking the unmanned aerial vehicle, and means for communicating through a cellular network; and

controlling the unmanned aerial vehicle with the user interface through the cellular network to cause the unmanned aerial vehicle to fly over the location in the field while providing to the user interface a live camera view of the field with the camera and an indication on the georeferenced aerial thermal image of where the unmanned aerial vehicle is over the field as the live camera view is acquired.

2. The method of claim 1 , wherein the portion of the field contains plants and the aerial thermal image comprises pixels indicative of different levels of thermal energy emitted by the plants within the portion of the field while the aircraft is in flight over the field, the method further comprising processing the aerial thermal image to assess relative variations in temperatures among the plants within the portion of the field by assessing variations in the pixels of the aerial thermal image.

3. The method of claim 1 , further comprising:

providing the georeferenced aerial thermal image to a handheld device located in the field; and

locating and displaying the present position of the handheld device on the georeferenced aerial thermal image.

4. The method of claim 1 , further comprising:

capturing still images of the field with the camera of the unmanned aerial vehicle while over the field; and

displaying on the user interface the location tracking of the unmanned aerial vehicle over the field and georeferenced locations of the still images captured with the camera of the unmanned aerial vehicle while over the field.

5. A system for analyzing a field, the system comprising:

an imaging system in an aircraft, the imaging system being operable to acquire an aerial thermal image of at least a portion of the field while the aircraft is in flight over the field;

means for georeferencing the aerial thermal image by superimposing the aerial thermal image on a geographical map of the field to obtain a georeferenced aerial thermal image;

means for overlaying the aerial thermal image on the geographical map;

an unmanned aerial vehicle having a camera for providing a live camera view of the field, means for location tracking the unmanned aerial vehicle, and means for communicating through a cellular network; and

a user interface having means for displaying the georeferenced aerial thermal image, means for indicating the location to be inspected on the georeferenced aerial thermal image, means for controlling the unmanned aerial vehicle through the cellular network to cause the unmanned aerial vehicle to fly over the location in the field while providing to the user interface the live camera view of the field and an indication on the georeferenced aerial thermal image of where the unmanned aerial vehicle is over the field as the live camera view is acquired.

6. The system of claim 5 , wherein the portion of the field contains plants and the aerial thermal image comprises pixels indicative of different levels of thermal energy emitted by the plants within the portion of the field while the aircraft is in flight over the field, the system further comprising means for processing the aerial thermal image to assess the relative variations in the temperatures among the plants by assessing variations in the pixels of the aerial thermal image.

7. The system of claim 5 , further comprising:

means for providing the aerial thermal image on the geographical map to a handheld device located in the field and having means for locating and displaying the present position of the handheld device on the georeferenced aerial thermal image.

8. The system of claim 5 , wherein the displaying means of the user interface further displays the location tracking of the unmanned aerial vehicle over the field and georeferenced locations of still images of the field captured with the camera of the unmanned aerial vehicle while over the field.
