OK.
First you need to know the coordinates of the area you want to see. In this case I used Wikipedia to see what are the coordinates for Jules Verne
crater. They are 35.0° S, 147.0° E
Knowing that, on the
Clementine Online Volumes page you have to look for
the volume that has the are you want. In this case it is volume cl_4032 from the "Full Resolution Clementine UVVIS Digital Image Model" section, so
I clicked the blue server icon on the right of the cl_4032 label to go to that online volume.
After that we are sent to the FTP page that corresponds to the volume chosen on the server chosen (in this case the USGS server in Arizona). On that
page it is easier to click on the "browse" folder, then on the "brbw.html" link that shows us a page with the photos for that volume in a
browsable version.
In this case I looked for the are you wanted and I reached the conclusion that it was further East, the coordinates for Jules Verne are too much to
the West of that area to be on this volume.
So I went back and selected the next volume to the East, the "cl_4038", I repeated the steps and found that one of the photos has part of the
triangles seen on the other image. The image I used was the first from the left on the third row from the top, image UI31S153.IMG
Once there you can click on "Large browse image" link to see the image (but in my case it gives me a "No such file or directory" error, or you can
click on the "full resolution image", which gave me a "No such file or directory" error again.
So I went back to the "cl_4038" page, selected the "data" folder and looked for the "UI31S153.IMG" file. I downloaded it and, after opening it
with "
The Gimp", (it can read those IMG files, they are not the old IMG file format that some image editing programs use) I
converted it to a PNG file and made a smaller version of the area with the triangle.
This is from the Online Volumes, reduced in size and with some brightness and contrast changed
This is "your" image
This is the PNG made directly from the downloaded "UI31S153.IMG" file.
I forgot to add that all online CD volumes have a "locator.htm" inside of the "browse" folder, like
this, where you can see what volume has the area you want.
