High Altitude Search for Jim Gray
We have now added the data captured by the NASA ER-2 plane yesterday over the ocean area outside of San Francisco. We were very fortunate that this flight was scheduled for yesterday and that the NASA folks were interested in having it capture these images. We have been able to split them just like yesterday’s satellite images and create HITs (Human Interface Tasks) from them.
The images are in this Mechanical Turn HIT Group.
The ER-2 is a high-altitude aircraft that replaced the famous U2 aircrafts of the cold war. For this run it was equipped with near-infrared cameras that make it extremely suitable for finding man-made reflective surfaces in a natural environment. Land will show up as red and sea as dark blue. Any foreign object in the sea would be bright, close to white.
PS: an earlier seperate group we created will be phased out, it was too confusing

Hey, I've been looking at the two HITs on Mturk, and they both show up as 774 and 619 HITs available, for at least the past few minutes. Is something "jammed" behind the scenes?
Hey. All of the current HITs are done. Thought you might want to know.
An ER-2, wow.
fyi. The images on mechanical turk are jpegs but they seem to have been downconverted from tiff. When I am generally trying to see something with different filters, I use the AVIS viewer which is dedicated to examine astronomy shots. By playing with the histogram and the threshold on the filters one can see a lot of things in very dark or very birght background. I am sure that photoshop does the same. Avis can import only tiff or other astronomical file formats (FITS,...).

I am sure this has already been looked into, but I put some explanation about what I meant in the previous post on the filters thresholds in this entry:
