Abstract: Systems and methods for the automated aerial application of chemicals onto agricultural areas. Unmanned aerial vehicles (UAVs) are configured to selectively attach to modular sprayer payloads, each payload having a payload reservoir, a spray nozzle, a pump, and a battery. A ground station having landing pads for the UAVs is configured to coordinate and automatically fill at least one payload reservoir from a material tank and provide the payload to a given UAV. A control subsystem can determine a mission plan and command the UAV to selectively deliver the contents of the payload reservoir to at least a portion of one or more agricultural areas.

Abstract: Systems and methods to analyze visible, near infrared, and thermal imagery of a land parcel in order to track and report changes to that land. A set of image processing techniques and algorithms can be utilized to generate composite images, align the imagery, compute differences, detect which features have changed, and meaningfully display the changed features. A moving window calculates differences in intensity between a first composite image and a second composite image and compares the differences against a threshold value. An interactive overlay user interface allows a user to adjust the magnitude and particular areas to be analyzed and presents the change.
