AI summary

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.
