Envi Met has quite a robust dataset of materials, however, it is still lacking in many surface materials you might find in the urban setting.

I can make my own materials, but finding the correct profile data to input for those materials is challenging, and I am not a material scientist enough to understand if those values I find are valid or not.

Has anybody found or know of a database that has been published or shared in the community with more materials? I imagine given all of the modeling in Envi Met in the academic and professional community, people have amassed quite the databases. I understand some may not want to share this, but maybe some do.

thanks in advance
