IberLit (Lithological map of the Iberian Peninsula for botanical studies)

A GIS layer (at 30 arc-second resolution) mapping nine major lithological classes potentially influencing plant distributions across the Iberian Peninsula. It was built using information from lithological maps of continental Spain (IGME, 2006), continental Portugal, Andorra and southern France (http://portal.onegeology.org/; Laxton et al., 2010), and it is provided in ASCII raster format.
