To create a simple exposure model for Taiwan we downloaded and used the GEM aggregated exposure model for Taiwan. This AEM is under CC BY-SA license and we are adding it to our datasources repository. The files are currently stored in the nextcloud folder as they need to be downloaded on the GEM website by filling a form and agreeing to terms and conditions.
I have compiled this folder to the best of my understanding, please have a look if you find any mistakes or anything I missed to add. Thanks.
