It’s not the first time that i do one of these only courses but i can tell, i have learnt a lot with this one. I strongly recommend it for those wanting to learn a bit more than the basics about remote sensing or GIS analysis. A comprehensive combination of ArcGIS tools and standard GIS knowledge is in very clear English, perfectly subtitled if needed and very easy to follow.
A must if you want/need to keep yourself updated!
