HeDi is an abbreviation for "Hail event Data interface" and is a project for collecting hail data and crop damage information for scientific studies with the support of volunteers in the whole Styria, Austria.
With this app, you can simply enter the information about a hailstorm and send it to Graz University of Technology.
With your crowdsourcing hail data, we know exactly when, where and in which size hail occurred. That helps us to better understand the weather phenomenon hail.
