1. A computer system for classifying the ages of trees in an area of interest, comprising; a processor that is configured to execute a series of programmed instructions to allow the processor to: create a false color composite image by using mid infrared data from three images for the area of interest that are each taken at different times as RGB color components for the false color composite image; convert the RGB color components of the false color composite image into color space data defining colors in the false color composite image; classify the colors in the false color composite image into a number of color classes; and assign an age to the color classes to produce a classified image of age classes of the area of interest.
