FloraMap is a system for producing the predicted distribution, or the areas of possible adaptation, for natural organisms when little or nothing is known of the detailed physiology of the organism. It is assumed that the climate at the point of collection of a set of individuals is representative of the environmental range of the organism. In the case of plants, these are usually germplasm collection accessions or herbarium specimens. The climate at these collection points is used as a calibration set to compute a climate probability model. The method uses a Fourier transform to standardize climatic timing and a principal components analysis (PCA) to produce a probability distribution in multiple dimensions. The principal component scores are used to map the probability surface from a set of interpolated climate surfaces. The system has been used to guide plant collecting, to investigate taxonomic and genetic variation, and to map crop pests and their potential predators.
