Images, from satellite and other airborne sensors, are more abundant and available than ever. Here are some tutorials designed to support introductory remote sensing activities.

Here is a link to the first Landsat LDCM image returned to Earth. This is the newest Landsat launched, I believe, in February, 2013.
A Closer Look at LDCM’s First Scene
Turning on new satellite instruments is like opening new eyes. This week, the Landsat Data Continuity Mission (LDCM) released its first images of Earth, collected at 1:40 p.m. EDT on March 18. The first image shows the meeting of the Great Plains with the Front Ranges of the Rocky Mountains in Wyoming and Colorado. The natural-color image shows the green coniferous forest of the mountains coming down to the dormant brown plains. The cities of Cheyenne, Fort Collins, Loveland, Longmont, Boulder and Denver string out from north to south. Popcorn clouds dot the plains while more complete cloud cover obscures the mountains.
