A graphical user interface facilitates methods for analyzing a temperature distribution across a scene that is captured by a thermal imaging device. Preferably, the interface includes a both a two-dimensional image of the captured scene and a three-dimensional representation of the captured scene. The three-dimensional representation is formed by a plurality of pixels, each of which are coded by a qualitative value from within a range of qualitative values, and each value, within the range, corresponds to a temperature. Each of the plurality of pixels is arranged, in a first and a second dimension of the three dimensions, according to a position of a corresponding pixel of the two-dimensional image, and, in a third dimension, according to a magnitude of the temperature associated therewith.
