You're right, this is a great area to apply various machine learning techniques! I'd recommend starting with the basics, such as spectral signatures and dimensionality reduction, before diving into more advanced methods.

I'm interested in the application of hyperspectral imaging in remote sensing. How effective is it in identifying various natural resources from space, compared to other techniques?

Hyperspectral imaging has proven to be very effective in remote sensing, particularly for detecting and identifying minerals, vegetation, and water resources in the earth's surface. It can provide more detailed information compared to other imaging techniques, such as multispectral or panchromatic imagery, due to its finer spectral resolution.
