When comparing multispectral and hyperspectral data it is not simply a case of “more data more better”! 

With hyperspectral you have “The curse of Dimensionality” but you also get more flexibility to pick exactly what bands you want to use!

With multispectral you have less noise but you also have less data!

This episode is designed to be a beginner's guide to the differences between hyperspectral and multispectral satellite data.
