This paper defines a land cover classification technique based on the annual NDVI cycle. A similarity measure based directly on thecomponents of the Discrete Fourier Transform is used to determine a pixels class membership. This Fourier component similarity measureproduces an objective, computationally inexpensive and rapid method of classification that is able to classify rangeland vegetation by dominantshrub type, and which performs favorably compared to previously published classification techniques. By also defining a Fourier component based coverage measure this technique provides an estimate of vegetation coverage.
