Some have heard about the Isotherm capabilities of the DJI Zenmuse XT but most don't know what it does or what it can be used for. Isotherm allows a XT equipped Inspire1 or M100 pilot to specify a temperature range that the XT with apply pixel emphasis or "highlights" to bring awareness to specific areas of within the live image. In the example video below, the obvious usage is Search and Rescue. This can also be applied to thresholds for an industrial purpose. For example, let's say that Electric Company XYZ had a sub-station in which transformers etc. needed to operate below 250 degrees at all times. The pilot could Isotherm on temperatures between 255 and 1000 degrees and then any component that fell within that temperature range would be highlighted on his screen -- all of this in real-time so that action can be taken immediately.
Again, this example is targeted toward SAR. I am hiding behind one of my shrubs in attempt to conceal most of my thermal signature. I use the RedHot palette in this example because RedHotiso happens to be one of my favorites for Isotherm.
