PAZ-PELLAT, Fernando et al. Design of a vegetation spectral index: NDVIcp. Agrociencia [online]. 2007, vol.41, n.5, pp.539-554. ISSN 2521-9766.

There are many vegetation indices (VI) based on relationships of the spectral space of the red and near infrared. In this study, the structure of the most widely used VI is examined, using a formulation to characterize curves of equal leaf area index. In order to solve the inconsistencies found in the VI, a new one (NDVIcp) is proposed, based on the correct structure of the problem, under empirical considerations. The NDVIcp is validated using data from field experiments with maize (Zea mays L.) and cotton (Gossipyum spp.).
