1: The SAR-EDU platform helps to teach remote sensing technologies and much more. It is definitely worth looking in to.
2: The LMU also has an interesting internet portal with loads of courses online, but they have all been written using the German language.
3: David Sandwell and others from the University of California also have some remote sensing lectures online which are well worth a closer look.
