Oooh, looks like the local university wants me to teach my GIS class again! Will get to work on improving my lectures. I will need to find another or different textbook, the one I used last time was only so-so... Any GIS folks here have any favorite books on practical use of satellite/remote imaging? (I used Lillesand's Remote Imaging and Interpretation, but it's less applied skills and mostly theory. Less math and algorithms, more concepts would be preferable--teaching this to Environmental Science and Resource Management students).
