The 'police' hereabouts use bottom mounted 'big bulge' thermal imaging devices on their low & slow aircraft to locate marijuana fields on state and federal lands. It seems that marijuana gives off a higher heat signature than the native vegetation. I knew what they used it for, but I didn't know what type they were or how they worked. Reading the descriptions after Googling 'thermal imaging' made me realize what the overflights were looking for...
