BioModelos is a collaborative online system to map species distributions. This repository stores functions to automate the construction of Species Distribution Models (SDM) from databases gathered, managed and curated by The Alexander Von Humboldt Institute and a network of experts in order to be evaluated and refined. The functions follow an automatized and flexible SDM general routine. First, it cleans occurrence data when is necessary and construct geographical areas in which those models will be trained. Second, they crops and masks current and future environmental variables. Third, the functions train SDM's using one or several algorithms, then evaluate them quantitatively and ensemble the best of each one. Fourth, they project to different scenarios at user discretion.

These data were created by grafting several existing shapefiles, and creating new ones in QGIS to fill in the voids. These data have an estimated accuracy of +/- 20 km. Given the fuzziness of a region I consider this acceptable for all pedagolical purposes, and most academic. Clearly points near the boundaries of these should be evaluated per user discretion. The author is very open to collaboration and updates of this product!!!
