From BISAGNI@FISH1.GSO.URI.EDU Wed Jun 28 13:02 EDT 1995 From: BISAGNI@FISH1.GSO.URI.EDU Date: Wed, 28 Jun 1995 13:02:04 -0400 (EDT) To: rgroman@globec.whoi.edu Subject: Xbrowse image details (Forward of earlier message) From: SMTP%"BISAGNI@fish1.gso.uri.edu" 10-MAY-1994 16:45:47.74 To: BISAGNI CC: Subj: Xbrowse Satellite Data Archive Now Available Date: Tue, 10 May 1994 16:42:56 -0400 (EDT) From: BISAGNI@fish1.gso.uri.edu To: ggball@plankton.whoi.edu, jimg@dcz.gso.uri.edu, dan@hollywood.gso.uri.edu, pete@uri.gso.uri.edu, carlw@chips1.gso.uri.edu, karls@chips2.gso.uri.edu Message-Id: <940510164256.208031ba@FISH1.GSO.URI.EDU> Subject: Xbrowse Satellite Data Archive Now Available I would like to inform all US-GLOBEC Georges Bank and Gulf of Maine Regional Marine Research Program PI's about near real-time, daily, satellite-derived sea surface temperature (SST) data, which cover Georges Bank and the Gulf of Maine and are available for browsing over the Internet. This browse capability is being made available via the Xbrowse (X-window based) client/server system developed by Jim Gallagher (jimg@dcz.gso.uri.edu) in Peter Cornillon's group located at the University of Rhode Island's Graduate School of Oceanography. In addition to visual "browsing" of the data, the Xbrowse system also allows the names of user-selected images to be listed in a file on your local host for later use in retrieving those images from the Xbrowse server via ftp. The latest Xbrowse client (ver. 3.3.7) and accessory files are available for SunOS 4.1.3 (Sun SPARC), OSF 1.3 (DEC Alpha) and Ultrix 4.3 (DECstation) via anonymous ftp from zeno.gso.uri.edu (/pub/xbrowse) and must be uncompressed, restored (via "tar") and properly installed on your local host for the system to work. At the present time all daily NOAA-11 Advanced Very High Resolution Radiometer satellite passes from 1 October 1993 up to the present day (generally 2 passes per day) have been remapped (earth-located) to our Georges Bank/Gulf of Maine "standard" region (given below) in a Mercator projection and are available for browsing from the image server located on dcz.gso.uri.edu. Our standard region is bounded by: 39.013 - 45.429 deg N latitude, and 63.487 - 72.164 deg W longitude. Precision navigation of each image on the server to within 1 or 2 pixels has begun with the image file names receiving a ".nav" file extension when navigation is completed. Be aware that "un- navigated" images (".rmp" file extension) may possess navigation errors of up to 6 or 7 pixels in the meridional and/or zonal directions. Daily remapping and weekly backups of these data will continue until after completion of the GLOBEC and Gulf of Maine field programs are completed. Each of these images are in University of Miami XDR04 format, consisting of an 8-bit, 512 X 512 pixel binary image, preceded by three 512-byte header records. The size of each image file (in uncompressed form) is ~250K bytes. Assuming that the client is properly installed on your local host, you can start the remote server by typing: xbrowse -server dcz.gso.uri.edu Those of you who have an earlier version of Xbrowse and would like access to the server should get an update because the latest version handles the Mercator projection properly. If you would like to download any of the images over the Internet to your local host for your own use, please contact me or Carl Wolfteich (carlw@chips1.gso.uri.edu) directly. Thank you.
