DTS (Discrete Trigonometric Spherical)

Discrete Trigonometric Spherical (DTS) transforms are mathematical techniques used to analyze functions on spherical surfaces by breaking them down into simpler trigonometric components, similar to how Fourier analysis decomposes signals into sine and cosine waves. DTS specifically applies to data defined on the surface of a sphere, enabling efficient representation and processing in applications like geophysics, computer graphics, and signal processing. It leverages discrete sampling points on the sphere to facilitate computations, helping to understand patterns, perform filtering, or compress spherical data effectively.
