Termogramm

Termogramm is a compound term used in several technical domains, and its precise meaning depends on context. In German-language sources, termogramm commonly refers to a thermogram, i.e., an image produced by thermography that encodes surface temperatures as colors on a two-dimensional plane. A thermogram is generated by infrared sensors and displays heat distribution across an object or body segment. These images are used in medical contexts to evaluate skin temperature patterns, in industrial and electrical inspections to detect hot spots, and in building diagnostics to identify heat losses. The termgram itself typically also relates to the color scale and the acquired temperature data, which can be analyzed to quantify hotter and cooler regions.

In a different usage, termogramm can denote a visualization of terms and their frequencies within a text or corpus. In this sense, it is akin to a term-frequency map, heatmap, or term distribution plot that highlights how often terms occur and how they are spread across sections or documents. This application is used in corpus linguistics and information retrieval for exploratory analysis, topic discovery, and quality control of indexing and metadata.

Because the termogramm is not a widely standardized term in English, it is important to verify domain-specific definitions. In many contexts, the standard terms thermogram (for the imaging) and term-frequency visualization (for text analytics) are preferred; termogramm may appear in German-language glossaries or in informal usage.
