This CD-ROM provides one of the most comprehensive photographic records of the planet Earth ever published for the consumer, each photo annotated with country and features coupled with a powerful navigational and search interface.

In addition to the complete photographic results, this ambitious space program is explained through the interactive use of text, sound and movies. The Space Radar Lab #1 flew on STS-59 to test various Radar instruments in space and collect the initial results for study by scientists. Many of the actual radar images of Earth with analysis are presented.

Perhaps most unique about this CD-ROM is the ability to view every one of the almost 13,000 photos taken by the astronauts (good and bad) along with the annotation of each picture by country name, general feature, time, and lat/long location. The pictures can be accessed in several ways.

Other features include: View the Shuttle position for each photo on a topographic map of the Earth in three different resolutions; animate the orbit; see the terminator; view the location of each image, complete with terminator; list cities near or in each photo; view a political map for each photo and read about each country; visit the astronauts and learn their backgrounds, view them at work and listen to extensive audio interviews; read the daily status reports for the mission from NASA; view the radar images, and their interpretations; search for visual photos near each radar image to compare the images; learn about the "Mission to Planet Earth", Earth Observing System and the Global Change Research programs. using the interactive handbooks; and read the Shuttle Handbook to learn all about the Space Shuttle. Export the text information the the clipboard, the printer or a file. An complete subject index for the CD-ROM permits jumping to a specific topic without navigation through the normal sections.

Geological Image Digitizing, Advanced Logging Technologies,Box 12009, Beaumont, TX, 77726, USA, 409 833-2130, Advanced Logging Technologies (ALT) scanning services specialize in the digitization of libraries of photographic prints, negatives, and slides at very low cost. Compare the cost of digitizing an 8X10 core photograph ($3) to the original cost of acquiring a high quality core photograph ($10-$25) and its original color and fidelity is preserved forever. A reasonable investment, when you consider the original cost of acquiring the image. Air is to photographic negatives and prints what smoke is to lungs, very damaging. Once an image is captured, its negative and print immediately begin deteriorating. Slowly, the original photograph will definitely degrade. We only have to browse through the family picture album to confirm this reality. Photographs should be digitized as soon as possible to preserve their original color and fidelity. Once a photograph is digitized, it immediately increases in value and becomes much more useful to your staff. A digital image can be instantly viewed, duplicated, analyzed, used in reports, and transferred to and from any desktop on your computer network. For many organizations that means world wide access; which is a far cry from a single photograph in a library of prints available at a storage site that only a few have access to. Processing photographic media is handled in a fully turnkey manner, from scanning to final image processing. Scanning is only the beginning of the process. All images are scanned in 32 bit color, have the white balance reset, digitally enhanced, and are saved in a customer selected file format. A minimum of two files are usually generated, one a high resolution JPEG or PhotoCD archive file and the other a lower resolution file to use in reports and catalogs. JPEG and PhotoCD are the principal formats used by ALT for high resolution image archiving because of their high compression rates and cross platform accessibility.
