Can you spare 5 minutes? The Global Earthquake Model (GEM) and the World Housing Encyclopedia need your expertise to improve our understanding of the global building stock. You can do this by describing a building or building type in your country using the TaxT tool. Your participation will assist GEM and WHE in generating a comprehensive, global building taxonomy and further the science of seismic risk reduction. All it takes is five minutes! Please send in your report and feedback by May 1, 2013.

The GEM Building Taxonomy is presented in tabular form and uses 13 main attributes to describe building characteristics. Before you get started or at anytime working with TaxT  please note that you can access the online taxonomy tables with a complete description for each attribute here.
