Anyone know what a good rule of thumb is for minimum GSD for a flat roof thermal image to identify heating/cooling leaks and/or water infiltration? 10cm/pixel? 5cm/pixel?
And how critical is it to use a radiometric camera when all you’re are doing is looking for significant temp differences and the accuracy of the actual temp isn’t that important? Seems like radiometric would have the main benefit on something like power utility inspection where you need to have accurate temp readings?
