Claim Text:
1. A method for generating a composite thermal image, comprising: receiving image data corresponding to a plurality of thermal images, wherein each of the thermal images corresponds to a subset portion of a geographical region, such that joining the plurality of thermal images forms a composite thermal image of the geographical region; analyzing the plurality of images to determine thermal range data for each of the plurality of images; analyzing the thermal range data for each of the plurality of thermal images to determine a global thermal range with a global minimum thermal value corresponding to a minimum thermal value of the plurality of thermal images and a global maximum thermal value corresponding to a maximum thermal value of the plurality of thermal images; adjusting a thermal level of each of the plurality of thermal images based on the global thermal range, such that a minimum value of the thermal range data for each of the plurality of thermal images is mapped relative to the global minimum thermal value, and a maximum value of the thermal range data for each of the plurality of thermal images is mapped relative to the global maximum thermal value; and generating a composite thermal image of the geographical region based on the plurality of mapped images that retains distinguishable temperature variations for each of the thermal images used for the composite image.
