Great! Thanks for the information!

Hello! I am new to the GIS world and as such have very limited knowledge of image analysis. My interest lies in identifying geothemal springs and mapping them. Large springs like Grand Prismatic Springs in Yellowstone can be observed on thermal imagery as seen in the attachment below (red arrow on the left). It creates a reproducible thermal "fingerprint" year after year. Does anyone have any suggestions regarding how to best scan/detect these thermal "fingerprints" over a large area. Is there software that will automatically compare images for these "fingerprints"? Perhaps something like this automatic landslide detection that compares images and indicates the probability of a Geothermal spring? Any guidance would be greatly appreciated! Ivan
