Snow, wind and seismic zones in Germany
Article updated on22 October 2024
The Eurocodes Zoning software allows you to obtain climatic and seismic zones free of charge from a GPS point in Germany. Take account of snow loads, the impact of wind and seismicity on your projects by finding your zones from your geographical data.
