Description: Sometimes image processing can get a little out of hand, as seems to be the case with this example of a Landsat 7 image of Cuprite, Nevada. A run-of-the-mill image in true color or even CIR, but apply an MNF filter or some kind of contrast stretch and... whoa! Is that still my image or someone’s lunch? It's the delicate balance inherent in using today’s image processing tools. We have the power to classify and sub-pixel-analyze to our heart’s delight, but what happens when the colors go awry and we’re not exactly sure what kind of digital monster we’ve created?
I at least know this: accidentally loading just the right bands after running an MNF filter in ENVI, I can print out a great conversation piece to hang up on my wall. I won't even tell you some of the names that have been submitted for it, but one of them involved Brussel sprouts (for the pivot crop fields in the left side of the image). 3 cheers for the power of remote sensing and its ability to cross over into modern art!

Description: On Maryland's eastern shore no-till soybeans show a wide range of phenological stage and field spectral reflectances even well into the summer season. In this region soybeans have a longer planting season than the other major field crops. Several stages of no-till soybeans are illustrated in this poster.

Description: This is a MODIS scene acquired over the central Aleutian Islands, Alaska, on 20 February 2001. High cirrus clouds such as this frequently form over the Aleutian islands and often result in large storms. This image was made by displaying Emissivity band 20, Reflectance band 17, and Reflectance band 26. This RGB image was then built into a 3D cube. All processing was done in ENVI.
Geographic location: Central Aleutian Islands, Alaska
Image resolution: MODIS - 500 meters
Source of imagery: The MODIS scene is courtesy of the International Observatory of the North (ION), University of Alaska Fairbanks (ion.gina.alaska.edu).
Image processing technique employed: This image was made by displaying Emissivity band 20, Reflectance band 17, and Reflectance band 26. This RGB image was then built into a 3D cube.

Do you think vendors and consultants choose proprietary interfaces over open ones to maintain "lock in" even when both are available?
