It consists many useful tools such as Grid Calculator (multiplying, adding rasters), Neighbourhood ( changing raster resolution) and Georeference Image. DIVA-GIS also has an Ecological Niche Modeling tool which can be used to predictive modeling ( it uses Bioclim and Domain algorithms). From DIVA-GIS desktop one can directly connect to DIVA-GIS Free GIS Data site and download climate grids, DEM, sattelite images or country level data.
