Astronomy Visualization Metadata

Astronomy Visualization Metadata (AVM) is a standard for tagging digital astronomical images stored in formats such as JPEG, GIF, PNG and TIFF. The AVM standard extends the concept of Extensible Metadata Platform (XMP) headers to include useful astronomical information about the subject of the image as well as the telescope used to take the image. This ensures that relevant information is transferred with the image when it is shared with others. AVM could be considered analogous to the FITS headers associated with raw astronomical data files.

The standard was proposed by the Virtual Astronomy Multimedia Project, part of the IAU Commission 55 and the International Virtual Observatory Alliance. It reached version 1.1 on May 14, 2008. The standard is currently used to tag images from the Chandra X-ray Observatory, Herschel Space Observatory, Spitzer Space Telescope, ESA/Hubble and the European Southern Observatory. Software packages such as PinpointWCS,FITS Liberator and Microsoft WorldWide Telescope have implemented the standard.

USS Norton Sound (AVM-1)

USS Norton Sound (AV-11/AVM-1) was originally built as a Currituck-class seaplane tender by Los Angeles Shipbuilding and Dry Dock Company, San Pedro, California. She was named for Norton Sound, a large inlet in West Alaska, between the Seward Peninsula and the mouths of the Yukon, north-east of the Bering Sea.

Career

Norton Sound (AV-11) was laid down 7 September 1942; launched 28 November 1943; sponsored by Mrs. Ernest L. Gunther, wife of Rear Admiral Ernest L. Gunther; and commissioned 8 January 1945, Captain Ben Scott Custer in command.

World War II

After Pacific shakedown, the new seaplane tender stood out from San Diego 26 February 1945 and steamed for Pearl Harbor, Hawaii. She reported to Commander, Marshall-Gilbert Area for training in mid-March, and she arrived Saipan 1 April 1945 to provide seaplane tending services.

Norton Sound anchored 1 May 1945 at Aka Kaikyo, Kerama Retto, and by 21 June 1945 had assisted in downing three hostile air raiders. Air alerts continued until midnight, 14 August 1945. Word of the Japanese surrender arrived eight hours later, and into September the tender engaged in upkeep and air operations at Okinawa.
