thank you for your question.
Yes, in the course we present a number of freely accessible spectral libraries containing different surface materials. In some cases, such as the LUCAS SOIL library, a registration is required prior to downloading the data.
There are more and more freely accessible spectral libraries becoming available such as the very recently released Open Soil Spectral Library (https://explorer.soilspectroscopy.org/). Please let us and your fellow students know here in the forum if you find out about more libraries. We may include them in the next version of the course.
