How to contribute

There are indeed several ways in which experts and researchers can contribute. A first step is our collaboration platform Nexus, where you can explore the work been developed by several working groups. Users and early adopters can use and test-drive the OpenQuake Engine and provide developers and scientists with useful insights on how GEM products respond to user’s needs.

You can contribute  to the GEM Building Taxonomy, and  complement it  by:

  • Creating and sharing Building Reports of buildings near you,
  • Providing feedback on the latest version of the GEM Building Taxonomy Report,
  • Providing feedback on Glossary definitions,
  • Sending in photos and other illustrations to improve the Glossary, following these simple instructions.

In addition  you can contribute to the Global Exposure Database (GED), the  first open database of global buildings and population distribution built for use at various scales of resolution (national, sub-national, municipal and building-to-building), by following these instructions. We are looking for (small) building datasets you are willing to share with GEM, or to receive other types of information you might possess on the buildings and their value in your country, region or city.

Developers can also contribute the OpenQuake development  following the instructions on this page.
