Say I have a geotiff (georeferenced) image file. And say this file was created by a thermal camera; so it is a thermal geotiff file. This thermal geotiff holds radiometric meta data (each pixel has a temperature value associated to it).
What I want to do is extract the GPS location of the high temperature area(s) [hot spots] within this thermal geotiff image. To clarify, obviously the image itself has a GPS coordinate in its meta data, but I want the GPS coordinate of a feature(s) within the image itself.
How can I extract the feature [temperature] location of the hotspots?
(Eg. If reading the radiometric meta data, then - return the GPS coordinates of each spot over 100 degC)
Or, these thermal geotiffs are also color coded (hot = red); so perhaps we could extract the GPS coordinates of each red spot.
Open to all comments/suggestions.
Thanks for reading.

Hi Vince,
ExifTool doesn't do any image processing. You need something that will analyze the image to extract the image to do this.
