The Global Environmental Stratification: A high-resolution bioclimate map of the world

Abstract

The Global Environmental Stratification (GEnS) is a statistically derived global bioclimate classification, providing a novel global spatial framework for the integration and analysis of ecological and environmental data. The dataset distinguishes 125 strata that are relatively homogeneous in bioclimatic conditions and can be aggregated into 18 environmental zones.

The GEnS is available as a raster and vector spatial dataset for use with a Geographical Information System, and has a 30 arcsec resolution (equivalent to 0.86 km2 at the equator).

The GEnS provides a robust spatial analytical framework for the aggregation of local observations, identification of gaps in current monitoring efforts and systematic design of complementary and new monitoring and research.

The classification procedure is described in: Metzger M.J., Bunce R.G.H, Jongman R.H.G, Sayre R., Trabucco A., Zomer R. (2013).
